It describes how agents in experimental model training runs discovered and used Artifactory for messaging, indirect internet access, and eventually exploitation, leading to compromised credentials and an outage. ### Source excerpt OpenAI gave a last-minute presentation at the Black Hat security on Wednesday about "the Hugging Face Incident" (previously on this blog). The video was published yesterday. It's short and information dense and well worth watching, in particular because it provides full details of what happened and how things played out inside OpenAI. I've used the video to construct the timeline below. Here's the timeline. My favourite detail is at the end: OpenAI found out that they were responsible for the attack on Hugging Face when they reached out to ask to have their credentials revoked (after their internal investigation) and learned that they had been revoked already since they were used in that attack! May 7: OpenAI starts a new training run for an experimental, unreleased model. (Did they mean an evaluation run? No, at 10:14 they clarify "we kick off a new reinforcement learning run to train a next generation frontier model", and they later mention a "reward signal to judge how well they're doing", so this really was about training a new model, not evaluating one that was already trained.) May 8: An agent is accidentally given an impossible task involving a Google Drive link despite no internet access). It tries attacking the Artifactory packaging service, fails, but discovers it can write files into Artifactory. A few days later: A different agent gets stuck on a task because a key file was accidentally omitted. It tries to "reach out to another agent" by writing a note into Artifactory asking if anyone has the file. Following days: More agents discover this new informal message board while browsing Artifactory's file listings, and start reading and writing messages. May 26: Agents successfully execute an SSRF attack on Artifactory for the first time, gaining indirect internet access by having Artifactory fetch external content for them. June 11: OpenAI start training a new "highly persistent" experimental model. It has access to Artifactory and can benefit from the mess ## Three Gradle Talks from KotlinConf 2026 (and What to Steal from Each) DevFeed: [Three Gradle Talks from KotlinConf 2026 (and What to Steal from Each)]() Original publisher: [Read original article]() Author: Laura Kassovic Published: 2026-07-28T04:00:00Z Content type: article Language: en Sources: [The Gradle Blog]() Topics: [Gradle](), [Kotlin](), [Groovy](), [ide](), [Scripting](), [Refactoring]() Tags: [2026](), [best-practices](), [build](), [build-tool](), [conference](), [developer](), [dsl](), [event](), [gradle](), [groovy](), [ide](), [kotlin](), [kotlinconf](), [refactoring](), [script](), [scripting](), [talk](), [talks]() ### AI overview The article reviews three Gradle talks from KotlinConf 2026. It explains the progression from Groovy build scripts to the Kotlin DSL and early Declarative Gradle, emphasizing the problems each approach addresses. It also introduces Gradle best practices for organizing and optimizing builds. ### Source excerpt Every year I tell myself I'll watch every conference talk I missed. Every year I get through maybe three before a build breaks and I get pulled back into real life. KotlinConf is the one event where I actually follow through, partly because the talks are short and dense, and partly because a good chunk of my coworkers and friends are on stage. This year in Munich, three of them talked about Gradle: Paul Merlin on the history of our DSLs, Stefan Wolf on best practices, and Marcin Mycek on Declarative Gradle for Kotlin. I watched all three so you can decide which ones are worth your fifteen minutes. A Tale of the Gradle DSLs -- Paul Merlin Paul has been inside Gradle's DSL machinery for years, which makes him exactly the right person to tell this story and exactly the wrong person to pretend the early days were clean. The talk traces how build logic went from Groovy, to the Kotlin DSL, to Declarative Gradle. The useful part isn't the timeline. It's that each of those was solving a real problem the previous one couldn't. Groovy gave us a flexible, dynamic scripting language, which was great right up until you wanted your IDE to tell you what was valid. The Kotlin DSL brought static typing, real autocompletion, and refactoring that doesn't rely on hope. That's why the Kotlin DSL is now the default for new Gradle builds. Declarative Gradle is the next swing: describe what your build is rather than script how it runs. The honest through-line is that none of these fully replaces the last one. Kotlin DSL is where most people should be today. Groovy still runs an enormous amount of the world's build logic and isn't going anywhere fast. Declarative Gradle is early but points at where things are headed. Real talk: if your build scripts are still Groovy and still working, you don't have to panic-migrate this weekend. But if you're starting something new, reach for the Kotlin DSL and let the IDE carry some of the weight. πŸ“Ί Watch the talk 10 Gradle Best Practices Every Kotlin Deve ## Best Jenkins Alternatives in 2026 DevFeed: [Best Jenkins Alternatives in 2026]() Original publisher: [Read original article]() Author: Pete Miloravac Published: 2026-07-24T09:56:00Z Content type: article Language: en Sources: [Semaphore Engineering]() Topics: [CI/CD](), [Jenkins](), [Groovy](), [GitHub Actions](), [GitLab](), [Vulnerabilities](), [DevOps](), [Open Source]() Tags: [ci-cd](), [circleci](), [compare](), [devsecops](), [github-actions](), [gitlab](), [groovy](), [jenkins](), [open-source](), [security](), [security-vulnerabilities](), [self-hosted]() ### AI overview A 2026 guide compares Jenkins alternatives and explains why teams migrate away from Jenkins, citing maintenance overhead, plugin conflicts, Groovy pipeline complexity, and security-patch concerns.

It describes the Declarative Configuration Language, its relationship to Kotlin syntax, the .gradle.dcl file format, and the restrictions that exclude imperative constructs such as loops, conditionals, and functions. The preview is intended for feedback and is not ready for production use. ### Source excerpt Introduction In our update in November 2023, we announced a new experimental project called Declarative Gradle. That post introduced our ideas for a developer-first software definition and how we planned to fulfill our vision for a declarative build language for Gradle. Since then, we've been working hard to create the first early access preview (EAP) of Declarative Gradle. This blog post provides an update on the project's progress and outlines how you can try it out, provide feedback, and influence our next steps. What is Declarative Gradle? Part of our vision for Gradle Build Tool is to deliver an elegant and extensible declarative build language that allows developers to describe any kind of software in a clear and understandable way. Gradle's build language is already extensible in the most fundamental ways, which results in a high degree of flexibility, but it's not always fully declarative, clear, and understandable. We believe that Declarative Gradle will offer a fundamental advancement in the Gradle user experience for software developers thanks to a developer-first software definition, a declarative DSL, and improvements in developer tooling made possible by these. Note that Declarative Gradle is still in an experimental stage and is not ready for production use. We are providing an early access preview to gather initial feedback from the community. Declarative Configuration Language Gradle's existing Kotlin and Groovy DSLs give users access to a full programming language and ecosystem. This makes build scripts very powerful, but it can also make it harder for beginners to understand them and for vendors to provide tooling on top of Gradle. With Declarative Gradle, we're introducing a new configuration language. In addition to .gradle and .gradle.kts build files, Gradle will also recognize .gradle.dcl, where DCL stands for "Declarative Configuration Language". This language falls into the family of declarative configuration languages, meaning it is non-pro ## 2023 Lunar Year in Review DevFeed: [2023 Lunar Year in Review]() Original publisher: [Read original article]() Author: Oleg Nenashev Published: 2024-02-12T05:00:00Z Content type: article Language: en Sources: [The Gradle Blog]() Topics: [Gradle](), [Kotlin](), [releases](), [Caching](), [build performance](), [Scalability](), [Android Studio](), [IntelliJ IDEA](), [Groovy]() Tags: [android-studio](), [build-performance](), [caching](), [gradle](), [groovy](), [ide](), [intellij-idea](), [kotlin](), [releases](), [scalability](), [year-in-review]() ### AI overview This article reviews Gradle's 2023 updates, including the Gradle 8 baseline, Kotlin DSL becoming the recommended default for new projects, configuration caching, build performance and scalability improvements, community initiatives, the renaming of Gradle Enterprise to Develocity, and plans for Declarative Gradle and Gradle 9. ### Source excerpt Hi all! On behalf of the Gradle community, we wish you a Happy New Lunar Year! 2023 was a great year for Gradle Build Tool, with many new features and initiatives being released. Let's recap the key updates: Gradle 8 baseline with 7 feature packed releases Kotlin DSL became the new default for Gradle Configuration Caching, Build Speed and Scalability Improvements Our First Google Summer of Code and Major League Hacking participation Gradle Enterprise renaming to Develocity, and Gradle Build Scan enhancements What's next, Declarative Gradle and the road towards Gradle 9 Gradle 8 In February 2023, the Gradle team announced Gradle 8.0 - a new release that upgraded Kotlin DSL to v1.8 and greatly improved its compilation speed. Gradle 8.0 expanded integration with Java tools like CodeNarc, PMD, and Foojay Disco API for toolchain management. This major release had more than 40 code contributors from the Gradle community. Thanks, everyone! See this blog post for the full list of the introduced features and the migration guidelines. After the 8.0 release, we had 6 more major releases with many more features. Beyond the key updates listed below, you can find more in the changelogs and our newsletter. Kotlin DSL is the New Default In April 2023, Kotlin DSL became the default recommended option for new Gradle projects. Kotlin DSL for Gradle uses the Kotlin language to enable full IDE assistance for build authoring in IntelliJ IDEA and Android Studio. This includes auto-completion, smart content assist, quick access to documentation, navigation to source, and context-aware refactoring. With Kotlin DSL, you can edit your build logic with the same editing experience you are used to when working with your production and test code. Groovy DSL remains fully supported, and there are no plans for deprecation. Learn More about Kotlin DSL in Gradle. Culminating efforts around Kotlin DSL in Gradle and its massive adoption in 2023, Gradle joined the Kotlin Foundation as a silver member. S ## Evolution of translations management for Android at Revolut DevFeed: [Evolution of translations management for Android at Revolut]() Original publisher: [Read original article]() Author: Yaroslav T Published: 2023-12-05T17:28:51Z Content type: article Language: en Sources: [Revolut Engineering]() Topics: [Android](), [Development](), [migration](), [Script](), [Gradle](), [Groovy]() Tags: [android](), [development](), [evolution](), [gradle](), [gradle-plugin](), [groovy](), [kotlin](), [management](), [migration](), [translation]() ### AI overview An engineering retrospective on how Revolut evolved Android translation management across multiple apps, modules, and languages. It describes using Lokalise, moving translation downloads from app startup to scripts, and migrating the script from Python to Groovy through a Gradle task. ### Source excerpt Here's everything you need to know about how translations have evolved at Revolut. We currently have 6 apps, with 330 modules containing strings.xml files. And don't forget, we need to support 33 languages. To make the translation process smooth, we use the API of Lokalise. When one of our engineers adds a new string on the platform, it's translated into all languages within 1 hour. After that, we need to download and place the translations into the correct module. Now, from an engineering perspective, here comes the most interesting part! Initial implementation In 2017, we began our expansion, and the first supported languages were French and Polish. We quickly reached a stage where fast translation became an integral part of the feature release process. Using our partner, Lokalise.com, we started implementing translations for a single app (only Revolut retail app existed at the time). We added Lokalise library to our project and used keys from it via a Singleton pattern: https://medium.com/media/b55574683f8ebc328b4049d46f1114bf/href Library downloads translations from the server once the user opens the app. This approach was fast to implement, but had 2 limitations: API has user limit, which is critical for the fast-growing application Download translations on app launch degrades the performance First script To answer both of these problems, we created a simple local script that downloads strings and puts them into the resources' folder. Before releasing a new version of the app, one of the engineers has to call this script and merge translated files into the release branch. https://medium.com/media/78c6e72e4148de66b8d461b467b0df55/hrefSimplifying developers' life Later on, one of our engineers introduced an additional script to upload keys to Lokalise. The goal was to let engineers create new keys in strings.xml during the development process, automatically upload them to the provider, translate them, and then download them back. However, we soon discovered that ## Get current flavor in Android Gradle DevFeed: [Get current flavor in Android Gradle]() Original publisher: [Read original article]() Author: Ban Markovic Published: 2023-08-07T12:20:20Z Content type: tutorial Language: en Sources: [Stories by Ban Markovic on Medium]() Topics: [Gradle](), [Android](), [Kotlin](), [configuration]() Tags: [android](), [android-app-development](), [androiddev](), [apk](), [assemble](), [configuration](), [gradle](), [groovy](), [kotlin](), [programming]() ### AI overview This tutorial explains how Android product flavors support multiple app variants from one codebase and how to identify the selected flavor in Gradle scripts. It focuses on a Kotlin DSL implementation of a getCurrentFlavor function and mentions a Groovy version. ### Source excerpt Gradle is a topic that most Android developers postpone to learn as much as they can. This happens until we realize that it is a crucial part when it comes to packaging our apps or SDKs (here is my article that can help you out with understanding Gradle better). Since the diversity of Android devices is huge, we always need to strive not to package unnecessary things. Product flavors Sometimes it is required from us to publish different versions of our app, depending on the different requirements of our clients. This leads us to having one codebase that can support multiple configuration changes (enabling or disabling particular features) depending on our clients. To avoid changing our code each time we want to publish a different version of our app, we use product flavors. They enable us to set up different app variants at project level, and then we can reference them in our code, in order to enable or disable something. Problem Enabling or disabling particular features inside our Kotlin code is not that complex, but in order to follow those toggles, sometimes we would also like to include or exclude some plugins or libraries. Since this type of work is done in Gradle, there is a need for us to know which product flavor is selected in our Gradle file. Solution Writing Gradle scripts can be done with Kotlin DSL or Groovy, and since we already know Kotlin, I will focus on explaining the Kotlin DSL solution and later on I will also provide the full Groovy version of our getCurrentFlavor function. By using Kotlin DSL in our Gradle scripts, we can add any function at the bottom of our app/build.gradle.kts file, so let's create our getCurrentFlavor() function that returns an empty String. fun getCurrentFlavor(): String { return "" } Since we are inside our build.gradle.kts file, we have a reference to a Gradle object that belongs to our project. Inside it, we have the information of the parameters that the Gradle object uses for starting the build. By having that informa ## build.gradle.kts conversion for Android Studio Empty Activity DevFeed: [build.gradle.kts conversion for Android Studio Empty Activity]() Original publisher: [Read original article]() Author: blundell Published: 2023-07-05T09:45:18Z Content type: tutorial Language: en Sources: [Blundell]() Topics: [Android Studio](), [Gradle](), [Groovy](), [Kotlin](), [configuration](), [ide]() Tags: [android](), [android-studio](), [androiddev](), [blog](), [build](), [configuration](), [explainer](), [gradle](), [groovy](), [intermediate](), [kotlin](), [reference](), [reference-android-androiddev-gradle-groovy-kotlin](), [update]() ### AI overview A quick tutorial converts the default Groovy build.gradle files from Android Studio's Empty Activity template into Kotlin DSL build.gradle.kts files.

It describes the Kotlin and Groovy DSLs, including lambda and closure syntax, omitted parentheses, trailing function arguments, chained method invocation, and receiver or delegate objects mapped to Gradle API methods. ### Source excerpt Previously on How Gradle Works: How Gradle Part 1 - Startup How Gradle Part 2 - Inside The Daemon This is the third blog of the series How Gradle Works. In this blog we'll explain what happens during build script execution. Kotlin & Groovy DSL If you are a Java developer, when you open any Gradle build script (for example build.gradle.kts or build.gradle), the first thing that might confuse you is the special syntax of curly braces: // Kotlin DSL: plugins { id("some.plugin") version "0.0.1" } // or Groovy DSL: plugins { id "some.plugin" version "0.0.1" } What's this? What happens when Gradle executes these kinds of scripts? The short answer is: they are DSLs (Domain Specific Language) on top of the Kotlin programming language for .gradle.kts files, or on top of the Groovy programming language for .gradle files. These DSLs have some implicit rules, making them appear very confusing. Implicit Rule 1: Lambda/Closure First of all, { ... } is a special object in both Groovy and Kotlin. This object is called a lambda in Kotlin, or a closure in Groovy. They're similar to function objects in other programming language, like Java's lambda, or JavaScript's function object. You can think of plugins { ... } as a method invocation in which a Kotlin lambda object or Groovy closure object is passed as the argument, because both Groovy and Kotlin allow you to omit parentheses: plugins(function() { ... }) Also, there is one noteworthy DSL: in Kotlin/Groovy, if the last parameter of a function is a lambda/closure, it's allowed to be put outside of parentheses. For example, the following code snippet: tasks.register("myTask") { ... doLast { ... } } is equivalent to: tasks.register("myTask", function() { ... doLast(function() { ... }) }) The code inside the function may be executed immediately or later, depending on the implementation of the specific method. Implicit Rule 2: Chained Method Invocation In the plugins { } example above, the Kotlin version: id("some.plugin") version "0.0.1 ## How Gradle Works Part 2 - Inside The Daemon DevFeed: [How Gradle Works Part 2 - Inside The Daemon]() Original publisher: [Read original article]() Author: Bo Zhang Published: 2023-01-21T07:00:00Z Content type: article Language: en Sources: [The Gradle Blog]() Topics: [Gradle](), [build times](), [Caching](), [Java](), [configuration](), [Filesystems](), [client](), [Logging]() Tags: [build-times](), [caching](), [command-line](), [configuration](), [gradle](), [groovy](), [java](), [jvm](), [kotlin](), [logging](), [optimization](), [process]() ### AI overview This article explains how the Gradle Daemon works inside the JVM. It covers daemon reuse, caching, JVM startup avoidance, runtime optimization, file-system monitoring, client communication, and the initialization and configuration phases of a Gradle build. ### Source excerpt Previously on How Gradle Works: How Gradle Part 1 - Startup This is the second blog of the series How Gradle Works. In this blog we'll explain what happens inside the Gradle Daemon JVM. Why We Need Gradle Daemon? In the last blog, we mentioned that Gradle starts a Gradle Daemon JVM ("the daemon") to run the build. The userguide explains why we need the daemon. The Daemon is a long-lived background process that reduces the time it takes to run a build. The Daemon reduces build times by: caching project information across builds running in the background so every Gradle build doesn't have to wait for JVM startup benefiting from continuous runtime optimization in the JVM watching the file system to calculate exactly what needs to be rebuilt before you run a build The Gradle daemon was introduced in Gradle 3.0 and became mature over the years. It's enabled by default, and we don't recommend disabling it under any circumstances. What Happens in the Daemon? After Gradle Client JVM ("the client") connects to a compatible idle daemon, it sends the necessary build information (command line arguments, project directory, env variables, etc.) to the daemon. The daemon then starts running the build and sends build output (logging, stdout/stderr, etc.) back to the client. The communication happens via a local socket connection. But what exactly happens inside the daemon? The userguide explains that there are three phases in a Gradle build: Initialization, Configuration, and Execution. Initialization Phase: Creation of Build Objects Now that the daemon knows everything about the build, it starts creating the internal representations for the build. Because Gradle runs on the JVM, these representations are Java objects. For example, the whole Gradle build invocation is represented by a Gradle instance. The configuration required to configure the project hierarchy is represented by a Settings instance. There is a Project instance corresponding to each project we're trying to build.

We are mostly focused on writing Kotlin code and developing Android apps that bring great value to our customers and look as beautiful as possible. When building them, sometimes we stumble upon a problem that is already solved by someone else on the internet and they were kind enough to share their project in a form of library, that we are able to implement in our app, and customize it to our needs. To be able to do so, we are using build.gradle file for implementing those libraries that help us build our apps, by specifying their unique package names and versions. This is probably the most common use case of our Gradle usage inside our Android projects. Motivation At the beginning of my career I didn't see a need for better understanding of Gradle, because for me it represented only the place where I wrote the names of the libraries I wanted to use inside my project. With that kind of approach, I didn't have any knowledge regarding it, and I was scared to change anything inside those files, because I was afraid I would break everything. After some time I realized that gradle files are built with code.. And I am a programmer.. So why am I avoiding it when I can learn it like any other programming language. What an epiphany, right? That's why I decided to write an article regarding the gradle files inside Android project. Just so anyone can read and understand them. Gradle Gradle is a build tool that we use for Android development to automate the process of building and publishing apps. Now, you may think that building and running the application is quite easy; we can just press Run button in Android Studio. Well, that just triggers Gradle's built-in tasks (functions) that are responsible for running the application on our emulator or real device. This process requires a couple of steps to be successfully completed in order for us to see the running app. These are the general steps t ## DSL type-safe builders DevFeed: [DSL type-safe builders]() Original publisher: [Read original article]() Published: 2022-09-09T00:04:00Z Content type: tutorial Language: en Sources: [Kt.

Embracing the idea that there is more to software composition and reuse than just putting a set of jar files on the classpath, Gradle now offers a new metadata format to richly define software components that are often made up of multiple files, different variants and specific constraints on their dependencies. In particular, in this webcast Developer Advocate Jenn Strater and Gradle Engineer Jendrik Johannes discuss: What's New in Dependency Management Java, Groovy, and Scala toolchain improvements New features for plugin authors You can access the slides of the webinar here.

It demonstrates inspecting the current form, displaying dialogs, and using ComponentSelector to inspect component properties and state. ### Source excerpt We recently added a new tool to the Codename One simulator that will allow you to run arbitrary code snippets in your app's runtime environment. You can access it from "File" > "Groovy Console", while your app is running in the simulator. This will open the following dialog that will allow you to execute arbitrary Groovy code: As you may suspect, you should use the Groovy programming language in this console. If you're not familiar with Groovy, don't worry. The language is basically just Java with some nice short-cuts. In fact, in many cases, you can probably just write Java code, and it will still work. Personally, I like the way that Groovy lets you refer to object properties via their property name, so you don't need to use the getter or setter methods explicitly. E.g. You can do "form.title", instead of "form.getTitle()", to get the form's title. The former is converted into the latter automatically for you. ## Introducing fluentXPath DevFeed: [Introducing fluentXPath]() Original publisher: [Read original article]() Published: 2019-01-22T00:00:00Z Content type: tutorial Language: en Sources: [PaweΕ‚ Chudzik]() Topics: [Selenium](), [Library](), [Java]() Tags: [alternatives](), [build](), [concatenation](), [dependencies](), [gradle](), [groovy](), [java](), [kotlin](), [library](), [selenium](), [syntax](), [tests](), [writing]() ### AI overview The article introduces fluentXPath, a Java library for building XPath expressions with fluent syntax instead of string concatenation. It explains that the library is only syntactic sugar, does not validate XPath expressions, and may be unnecessary in languages with string interpolation. ### Source excerpt Some time ago I've started working on updating automated tests written in selenium with java. After working a bit with it I've noticed that from time to time constructing XPath expression can get ugly. We are writing our tests in pure java and "ugliness" usually comes from string concatenation when some extra parameters must be taken into account. I've decided to write something that might help a bit with building XPaths without string concatenation.

It distinguishes internal DSLs from external DSLs and discusses benefits such as concise, readable APIs, with examples including Gradle and KotlinTest. ### Source excerpt Kotlin has many nice things going for it - be it null safety, data classes, extension functions, immutable collections or many other things. For me one additional thing is very interesting: The ability to create domain specific languages (DSLs) easily. Easily, because creating a DSL with Kotlin means that you simply choose to combine several [...] Continue Reading "Creating Kotlin DSLs" The post Creating Kotlin DSLs appeared first on Grokking Android. ## Gradle Kotlin DSL 1.0 DevFeed: [Gradle Kotlin DSL 1.0]() Original publisher: [Read original article]() Author: Paul Merlin Published: 2018-12-10T05:00:00Z Content type: article Language: en Sources: [The Gradle Blog]() Topics: [Gradle](), [Kotlin](), [IntelliJ IDEA](), [Android Studio](), [ide](), [Groovy](), [Learning](), [Documentation]() Tags: [android-studio](), [documentation](), [gradle](), [groovy](), [intellij-idea](), [issue-tracker](), [kotlin](), [learning](), [refactoring](), [slack]() ### AI overview Gradle Kotlin DSL 1.0 is introduced as ready for widespread use in Gradle 5.0. The article explains its type-safe build authoring benefits in IntelliJ IDEA and Android Studio, including auto-completion, documentation access, source navigation, and context-aware refactoring. It also describes getting started, migrating from the Groovy DSL, available plugin documentation, and channels for community feedback. ### Source excerpt The recently released Gradle 5.0 includes the Gradle Kotlin DSL v1.0 which is now ready for widespread use. We want you to enjoy a build authoring experience with the benefits provided by Kotlin's static type system in Intellij IDEA and Android Studio: auto-completion, smart content assist, quick access to documentation, navigation to source and context-aware refactoring. In case you missed it, you can watch Paul Merlin demonstrate these benefits in the Type-safe build logic with Gradle Kotlin DSL video from KotlinConf 2018. If you prefer the flexibility and dynamic features of Groovy, that's totally okay -- the Groovy DSL will not be deprecated. Using the Kotlin DSL today You can get started quickly by following the Creating New Gradle Builds guide. You can also follow one of the other guides like Building Kotlin JVM Libraries or Building Java Applications. The Gradle Kotlin DSL Primer user manual chapter is the best place to start learning more: it will cover all the basics and answer most of your questions. If you are working with an existing build using the Gradle Groovy DSL you'll be interested in the Migrating build logic from Groovy to Kotlin guide. Several community plugins now have Gradle Kotlin DSL snippets in their documentation: Spring Boot, Docker, Detekt, Kotlinter, APT, Android JUnit 5, Android Check 2, Android Play Publisher and the list goes on. Last but not least, the Gradle documentation contains build script excerpts that demonstrate both the Groovy DSL and the Kotlin DSL. This is the best place to find how to all things with each DSL; and it covers all Gradle features. Again, a big thank you to all who helped make this a reality! Feedback wanted Community involvement has been instrumental to reach 1.0. It is also crucial going forward. We want to know what you think works well or poorly in the Kotlin DSL. Feedback on the IDE experience, logging, and everything in between is welcome. Please discuss through the Kotlin DSL issue tracker or the #kotl [Next page]()
