Hi,

After upgrading git client plugin from 1.19.6 to 2.0.0 and git plugin from 2.4.4 to 3.0.0, I got the following error

Caused by: java.lang.NoSuchMethodError: org.eclipse.jgit.revwalk.RevWalk.release()V 3.0.0 => 2.

Please advise. Thank you.

You'll need to downgrade git client plugin back to the previous version.  The git client plugin upgrade from 1.x to 2.0 introduces a breaking change by switching from JGit 3 to JGit 4, and by changing from Java 6 compatible to Java 7 compatible and by switching from requiring a minimum of Jenkins 1.532 to a minimum of Jenkins 1.625.

Unfortunately, the JGit API does not retain full compatibility between JGit 3 and JGit 4.  That "no such method exception" is one of the indicators of that incompatibility.

A work around can be applied to a future version of the gerrit trigger plugin, as was used in the git plugin.  The maintainer of the gerrtit trigger plugin can contact me for more details if they are needed.

Looking at the log for gerrit-trigger [1],  it seems you need to update it as well (Mark supplied a fix for this problem).
