It presents the incident timeline, the effects on builds, the fixes deployed, and measures to reduce reliance on JCenter, including repository content filtering, metadata sources, an internal mirror, and Maven Central. ### Source excerpt On January 12th 2022, Gradle users were experiencing issues resolving plugins from the Gradle Plugin Portal because of the outage of JCenter that the Plugin Portal depends on for some of the functionality. This postmortem gives a timeline of the outage, describes the effect on Gradle users, and what actions were taken to further reduce the Gradle Plugin Portal's reliance on JCenter. Finally, we will also discuss how you can protect your build against such outages. Users affected by JCenter outages for project dependencies should also refer to our original blog post about the shutdown of JCenter. Outage timeline 4.30pm UTC, January 12th Outage begins Gradle users start noticing that plugin resolution is failing in builds. 4.56pm UTC, January 12th Incident opened The outage is acknowledged on the Gradle status page. 6pm UTC, January 12th We identify a hotfix that will allow the Gradle Plugin Portal to ignore 5xx error codes from JCenter and resolve plugins it hosts entirely. However, the hotfix cannot be built and deployed immediately because building the Plugin Portal code requires resolving some plugins from the Plugin Portal itself and JCenter, which failed. 8.44pm UTC, January 12th First fix is deployed We update the build of the Plugin Portal to not rely on JCenter at all by using repository content filtering and supported metadata sources. The first fix is deployed. 8.58pm UTC, January 12th Second fix is deployed The first fix turns out to be insufficient. We develop and deploy a second fix that allows us to change the repository to which the Plugin Portal redirects. We configure the Plugin Portal to use our internal mirror of JCenter. 9.43pm UTC, January 12th Outage is resolved The existing mirror is too sparsely populated as it was not used much, which means most builds still fail to resolve plugins. We update the mirror repository to redirect to Maven Central as well. This results in most dependencies being properly resolved and unblocked most builds. Plugins ## JCenter Shutdown Impact on Gradle Builds DevFeed: [JCenter Shutdown Impact on Gradle Builds]() Original publisher: [Read original article]() Author: Sterling Greene Published: 2021-02-22T05:00:00Z Content type: article Language: en Sources: [The Gradle Blog]() Topics: [Gradle](), [Maven](), [Security](), [Git](), [GitHub]() Tags: [bintray](), [build](), [central](), [dependencies](), [documentation](), [github](), [gradle](), [jfrog](), [maven-central](), [mirror](), [packages](), [pipelines](), [release](), [update]() ### AI overview This article explains how the shutdown of Bintray and JCenter could disrupt Gradle builds by affecting dependency resolution, plugin dependencies, and package publishing. It describes JCenter's relationship to Maven Central, notes that JCenter became read-only indefinitely, and recommends moving builds and publishing workflows to other repositories, with Maven Central becoming Gradle's default in new samples and init templates. ### Source excerpt ℹ Update on July 15, 2024 See our recent blog post for up-to-date information about the Plugin Portal and JCenter. On February 3 2021, JFrog announced that they will be shutting down Bintray and JCenter. This post tells you what you need to know and do to avoid disruptions to your build pipelines. Your build may be affected by this shutdown in several ways: Gradle may not be able to download the dependencies used to compile, test or run your code. Gradle may not be able to download the dependencies used by plugins to configure your build. Gradle may no longer be able to publish your package to Bintray. Additionally, you should be aware of the security considerations when moving from one repository to another. UPDATE: JFrog has decided to keep JCenter as a read-only repository indefinitely. New package and versions are no longer accepted on JCenter. All Bintray services have been shutdown. Background JCenter is a central artifact repository, like Maven Central. Software projects use JCenter to distribute their software to other people. JCenter also serves as a mirror for Maven Central, so any dependencies available on Maven Central are also available on JCenter (but not vice versa). Bintray is a management layer that software projects use to publish and promote packages to JCenter. Bintray also allowed users to create public user-specific repositories that were isolated from JCenter. Both of these services are affected by the shutdown. Impact to builds By default, Gradle does not add an artifact repository to your project; however, Gradle does provide a convenient API for using the JCenter repository. The Gradle Build Init plugin produces build templates that use the JCenter repository to resolve dependencies. In many code examples and documentation, JCenter is used as an example repository. It's very likely that you have builds that rely on JCenter. We've found over a million Git repositories on GitHub that use JCenter with Gradle.

Po pewnym czasie jest ich już kilka... W którymś momencie dostrzega się zalety wirtualizacji i na kilku maszynach fizycznych działa kilkanaście czy kilkadziesiąt maszyn wirtualnych. W takiej sytuacji pobieranie aktualizacji dla wszystkich maszyn potrafi mocno zabić łącze. I w tym momencie zaczynamy się zastanawiać czy może nie warto byłoby zrobić własnego mirror'a paczek dla naszego ulubionego distro... do prywatnego użytku... synchronizowanego w nocy by nikomu nie przeszkadzać... i dostępnego nawet gdy będziemy offline... Zaczynamy liczyć miejsce i okazuje się że repozytorium Debiana dla architektury i386 to prawie 60GB (sic!), no ale mamy kilka maszynek z arch amd64 i tutaj też prawie 60GB - auć. W tym miejscu wielu dochodzi do wniosku że to jeszcze nie pora na własnego mirror'a 😃
