Jenkins cannot access git

Question

After a crash of the Jenkins server, I cannot start my projects builds.

I get this weird message. Any clues?

hudson.plugins.git.GitException: Command "git fetch --tags --progress origin +refs/heads/master:refs/remotes/origin/master --prune" returned status code 128:

Answer 1

Had the same a few times.

Sometimes the answer of @"Mukesh M" may help - that is a decent approach. In other cases, the following approach helped me a few times.

First visit the /var/jenkins_home/caches folder. Delete the git-hashes. The next start of the job will retrieve everything from git again so the job will run smooth again. So omitting the git cache.

Answer 2

In my case I did following

Select Workspace and click on Wipe Out Current Workspace. This will delete your workspace.

Now just start new build and it will work.
