Welcome to another rip-roarin' installment of This Week in Spring! It's a fabulous and fun day here in Paris, France, as I wait to board the train to Amsterdam for the IntelliJ IDEA conference! It's going to be amazing. We've got another incredible week's roundup to dive into, so let's do it! I feel like some of the best content over the past several months in this weekly roundup has been Craig Walls' Spring AI Recipes section. Fantastic stuff! This latest one looks at running an LLM in-JVM This is a nice article on using vertical slices in Spring Boot on Solodev.sk, by Dominik. Well done! Another amazing installment from Craig Walls, this one looking at running against local LLMs My friend and colleague DaShaun Carter talks about his Spring AI starter for agents.md Craig also has this lovely post on efficient tool use in Spring AI Last week, I did two videos on using Spring Boot, JavaFX, GraalVM native images, and Spring Security (and PKCE) to build native, lightning-fast, dynamic, efficient, reusable desktop applications that run well on Mac, Windows, and Linux, and look amazing, while taking small fractions of the RAM of a similar Electron-based application. Here's the first one, showing how to use Spring Boot and JavaFX together, so that you get the component model, event dispatch subsystem, internationalization, lifecycle management, and, of course, the entire and very rich ecosystem of Spring components and can use them to manage JavaFX components, too. We also look at native image compilation. Here's the second video, which looks at using Spring Security's OAuth client in the context of a desktop application, which can not, by definition, hold a client secret.

It describes benchmarking a small Spring Boot project in a Docker environment and cautions that the measurements are approximate and specific to Gradle 9.5.1 and the stated test setup. ### Source excerpt In Part 1 and Part 2, we optimized Gradle's Startup and Configuration phases on ephemeral CI. In this final part, we reach the Execution phase: the point where Gradle checks whether task outputs can be reused and, when they cannot, runs the selected tasks. This is where the Gradle Build Cache becomes the main lever. Benchmarking Performance in Ephemeral CI The methodology is unchanged from Part 1 and Part 2: each scenario builds a fresh Docker image of the Spring Boot Project with --no-cache, base images are pre-pulled, and every figure is the average of ten runs against one consistent baseline. Individual runs vary by a second or two, so read small differences as approximate rather than exact. These numbers are not intended as universal Gradle performance claims. They show the relative impact of execution-phase optimizations for one small Spring Boot project, one Gradle version, one JDK image, and one local Docker environment. Larger builds, especially multi-module builds with expensive compilation, testing, code generation, or packaging tasks, will generally see bigger gains from task-output reuse than this sample project does. NOTE: All measurements in this post are pinned to Gradle 9.5.1. If you repeat the experiment with a newer Gradle version, rebuild the prime image and update any version-specific cache paths accordingly. The baseline (no optimizations) averaged 32.3s over ten runs, in line with the ~31.5s baselines from Parts 1 and 2. Optimizations for the Execution Phase During the Execution phase, Gradle runs the task graph that was selected and ordered during configuration. For each task, Gradle decides whether work can be avoided before it executes task actions: Input and output snapshotting: Gradle fingerprints the task's declared inputs, outputs, and relevant implementation details. Reuse checks: Gradle determines whether the task is already up to date locally, or whether matching outputs can be loaded from the Build Cache. Task action execution: Gradl ## Essential Tips for Gradle on Ephemeral CI Environments - Part 2 DevFeed: [Essential Tips for Gradle on Ephemeral CI Environments - Part 2]() Original publisher: [Read original article]() Author: Louis Jacomet Published: 2026-07-08T04:00:00Z Content type: article Language: en Sources: [The Gradle Blog]() Topics: [Gradle](), [Caching](), [benchmarking](), [Spring Boot](), [Docker](), [GitHub]() Tags: [benchmarking](), [build-performance](), [cache](), [docker](), [github](), [gradle](), [jdk](), [spring-boot]() ### AI overview Part 2 examines Gradle configuration-phase performance in ephemeral CI environments, focusing on dependency and script caching and the roles of the setup-gradle GitHub Action and Develocity Universal Cache. ### Source excerpt In Part 1, we explored foundational strategies for improving Gradle build performance in ephemeral CI environments, focusing on the Startup and Initialization phase. Now, in Part 2, we shift our focus to the Configuration phase: the work Gradle does after startup but before it executes any tasks. We'll benchmark dependency and script caching, then look at where the setup-gradle GitHub Action and Develocity's Universal Cache fit. Benchmarking Performance in Ephemeral CI The methodology is the same as in Part 1: each scenario builds a fresh Docker image of the Spring Boot Project with --no-cache, base images are pre-pulled, and every figure is the average of ten runs against one consistent baseline. Individual runs vary by a second or two, so read small differences as approximate rather than exact. These numbers are not intended as universal Gradle performance claims. They show the relative impact of configuration-phase optimizations for one small Spring Boot project, one Gradle version, one JDK image, and one local Docker environment. Larger builds, with more dependencies and more build logic, will generally see bigger gains from dependency and script caching than a small sample project does. NOTE: All measurements in this post are pinned to Gradle 9.5.1. If you repeat the experiment with a newer Gradle version, rebuild the prime image and update any version-specific cache paths accordingly. One difference from Part 1: for the Configuration phase, we prime the cache by building the complete Spring Boot Project, not the empty Prime Project. Caching configuration-phase work only means something when there are real dependencies and real build scripts to cache, so the prime image must reflect a realistic project. As in Part 1, that prime image is built once and only restored from, so the timed builds measure cache restore, not cache creation. Building the full project populates the following directories in the Gradle User Home: .gradle/ <-- Gradle User Home (default: ~/. ## Измерь меня, если сможешь: как проводить ревью работы команды через призму метрик DevFeed: [Измерь меня, если сможешь: как проводить ревью работы команды через призму метрик]() Original publisher: [Read original article]() Author: Xanderblinov (hh.ru, Конференции Олега Бунина (Онтико)) Published: 2026-06-16T05:30:14Z Content type: opinion Language: ru Sources: [HeadHunter RU]() Topics: [lead time](), [Spring Boot]() Tags: [hh-ru](), [lead-time](), [spring-boot](), [tag-1fa41e7deaba](), [tag-3aa328ccc6ec](), [tag-4e7e01a57307](), [tag-b92bf5906bbd](), [tag-c607c3dc8776](), [tag-c6d5400b7d88]() ### AI overview A technical lead at hh.ru explains how the company reviews team performance through metrics.
