My lts-with-plugins repo, in the caches directory
The JGitAPIImpl prune implementation logs a message that it is unable to remove path. Possible behavioral change in the transition from JGit 4.5.4 to JGIt 5.0.2.
Stack trace indicates it is happening in the caches directory used by a multi-branch project. The referenced directory is not empty. The message is correct, but if deletion is not expected to succeed and is harmless, the exception should be accepted and suppressed.
