error fetching git repo

[Eyal Edri]

Hi,

I've been seeing this error lately using the latest Jenkins (1.414) and
git plugin (1.9).
I've followed the guide on the plugin page and changed 'git' to the full
path of git, but it didn't solved the problem.

Usually running the same job again immediately after succeeds.

is this a bug? Or it happens due to network errors?

Thanks,

This is nothing to do with the plugin - this is the underlying repository that's broken somehow. All the output in the error is coming from the git commandline (you can verify this by cd-ing into the directory and retrying natively).

I'd check 'git --version' that it isn't some ancient version, and if it isn't probably google for the git error.

I noticed it happens when we create a new tag or branch on the git repo.

And the git plugin thinks it’s a code change via the poll and for some reason fails.

 

Is it a bug or misconfiguration of the plugin?

Can we avoid this error?

 

Thanks,
