      We are currently investigating the issue. Traffic against the plugin portal has increased heavily this week, with a serious uptake in traffic from user agents identifying as Renovate and some specific source IPs having increased traffic from nearly nothing to multiple millions requests an hour.

    JCenter no longer serves files but redirects to Maven Central instead

    1. June 23, 2023 at 9:14 AM UTCinvestigating

      Without any prior announcement, it looks like JCenter is now redirecting to Maven Central instead of serving artifacts. Builds that have build logic that relies on artifacts available only on JCenter and not Maven Central will fail. We are investigating what we can do to mitigate the issue. We also contacted JFrog to understand this change.

    2. June 23, 2023 at 6:48 PM UTCmonitoring

      JCenter is now serving artifacts again. We're monitoring if this has resolved the situation and we'll provide more information later.

      JCenter has expired SSL certificates, the Plugin Portal now uses Maven Central has its backing repository. This will cause issue for libraries that are available on JCenter but not Maven Central. This can include older versions of plugins.

      The issue appears to be upstream. We're monitoring for failures and will take action if failures increase.

    3. November 7, 2022 at 11:58 PM UTCmonitoring

      We received more reports that some dependency downloads are failing from jcenter.bintray.com. For now, we've changed the backend to redirect to Maven Central. You may notice some redirects to JCenter for the next few hours until caches expire. Unfortunately, this means artifacts that were only available on JCenter/Bintray and were never migrated to Maven Central will not be available from the Plugin Portal. If you are using dependency verification, you may also notice different artifact checksums for libraries that were re-uploaded to Maven Central. We'll continue to monitor the situation.

    4. November 8, 2022 at 4:01 PM UTCmonitoring

      We've restored the redirect to JCenter. You may notice some redirects to Maven Central for the next few hours until caches expire. We will continue to monitor for increased failures.

      While the mirroring put in place alleviates some of the JCenter being down impact, the mirror is a bit out of date and currently cannot sync recent artifacts. This continues to impact builds.

    2. October 31, 2022 at 1:26 PM UTCresolved

      The new settings have resolved most of the issues. Note that you may still experience problems if the package only exists on JCenter and was never mirrored until now.
