I have configured a job to verify Gerrit changes, but it fails with NPE. Here's the log:

[JENKINS-30844] NPE on Gerrit job
Gerrit Trigger - 2.16.0
GIT client plugin - 1.19.0
GIT plugin - 2.4.0
Additional Behaviours - Choosing strategy: Gerrit Trigger
After further investigation it seems that the problem is related to the Branch Specifier. If "Branches to build" is blank it is replaced with "**" and the error occurs. Replacing it with $GERRIT_BRANCH fixed the configuration.
The GitTagAction constructor is no longer called by the git plugin during checkout unless the administrator has enabled GitTagAction intentionally. Git plugin 4.5.0 removed the git tag action by default. The global configuration documentation provides more details.
Can you describe the job configuration, the steps necessary to duplicate the problem, and the version numbers of the various plugins involved in seeing the problem?
For example, I assume you must have added the Additional Behaviour to tag every build. Are there other behaviors you added which might be interacting with this? Does the failure occur even without involving Gerrit (since the stack trace looks like it is purely a git plugin stack trace, not involving anything with Gerrit).
