git plugin 4.0.0 and git client plugin 3.0.0
Core issue: JGit doesn't support git-worktree yet.
Trigger: git-plugin tries to retrieve the commit message via JGit in order to print it to the log, fails the build on error
Possible short-term solution: make printing the commit message optional
Possible short-term solution: make errors while printing the commit message not fail the build
Possible long-term solution: fix JGit to support git-worktree
Possible long-term solution: stop using JGit

This previously worked. Likely up to git-plugin 3.3.0.
If I add a catch clause for org.eclipse.jgit.errors.MissingObjectException, rebuild and install the plugin, I can run my build.
