Anything else?

Yesterday everything worked fine, ive updated some plugins today and this started to happen

Are you interested in contributing a fix?

No response

[tomasbjerre]

Looks like a classpath issue when used with those other plugins you updated.

Can you find out which other plugins you need to downgrade to make it work again?

[Taelyn]

Git Client v6.0.0 is the issue
downgraded to v5.0.0 and it works fine

https://updates.jenkins.io/download/plugins/git-client/

Can you fix this?

[MarkEWaite]

Git Client v6.0.0 is the issue downgraded to v5.0.0 and it works fine

https://updates.jenkins.io/download/plugins/git-client/

Can you fix this?

The library se.bjurr.gitchangelog:changelog-lib has made the same (flawed) choice that the Jenkins git client plugin made. It has chosen to ignore the JGit deprecation of the peel method on the Repository object. JGit 7.0.0 removed the peel method from the Repository object after multiple releases where the method had been deprecated.

The library se.bjurr.gitchangelog:changelog-lib needs to be updated to replace its use of methods that are deprecated in JGit, especially those methods that have been removed in JGit 7.0.0.

Examples of the types of changes that are needed in that library are available in the git client plugin in:

• Use JGit 7.0.0, require Java 17 and Jenkins 2.463 or newer git-client-plugin#1170

The short term workaround is noted by @Taelyn - use git client plugin 5.0.0 or earlier. The fix is to update changelog-lib to use methods that exist in both older JGit and JGit 7.0.0.

[tomasbjerre]

I just released 2.2.0 of git-changelog-lib.
And released this plugin as 3.39 with that version.

Open issue again if not working.

[MarkEWaite]

Thanks very much for the rapid response @tomasbjerre!

There is a complication hiding in the choice to upgrade the library to rely on JGit 7.0.0. JGit 7.0.0 requires Java 17 but the git changelog plugin supports Jenkins 2.462.1 and Jenkins 2.462.1 still supports Java 11. A few alternatives for consideration:

• Switch the library back to depend on its previous JGit version while retaining the code changes that adapt to the deprecations and JGit 7.0.0 removals. That allows the plugin to be used on Jenkins 2.462.x
• Switch the plugin to require Jenkins 2.463 or newer so that users don't attempt to run the plugin on a Jenkins version that does not have JGit 7.0.0 available. That requires existing users to upgrade to 2.463 or newer (2.476 is the latest Jenkins weekly)

I think that the first alternative is likely better for the users, since they can upgrade to the latest git changelog plugin without upgrading their Jenkins controller to a weekly release.

[tomasbjerre]

I'm making a new release with 2.463 to require Java 17. The library already requires Java 17 because of Handlebars dependency.
