All authenticated Git operations from Master node fail

[Ben Coo]

When attempting to perform an authenticated Git operation from our Master node through Jenkins, it will always fail with the following error:

hudson.plugins.git.GitException: Command "C:\Program Files\Git\bin\git.exe ls-remote -h <address-to-repo>.git" returned status code 128:

This applies to both SSH and HTTP authentication. Performing the exact same operations directly on the server and/or using JGit works as expected. We had originally been using JGit for operations performed on the master node (Polling, SCM checkout of Pipelines, etc) as a workaround, but applying Git Polling from within a Pipeline script (Jenkinsfile) appears to override the JGit specification and use the CLI Git instead, resulting in polling always failing due to the error above.

I get the same result whether I define the Global Tool as "git" or if I give the full path "C:\Program Files\Git\bin\git.exe". The location of ssh.exe is defined as the GIT_SSH env variable. I did this based on a StackOverflow answer to hopefully get somewhere based on the direct error that Git was reporting through the plugin.

I have also done a fresh uninstall-reinstall of Git for Windows (multiple times) with no change.

Environment:

• Windows Server 2012
• Jenkins 2.60 LTS
• Latest version of git-plugin and git-client-plugin (3.3.2 & 2.4.6)
