If I'm reading the source code correctly, that line in the source code (line 77 in UserRemoteConfig of the git plugin) is trying to find the default Git installation. If that default Git installation finding method returns null, I think a null pointer exception will result since the value of the finding method is immediately used for another call. It might be worth attempting to configure the location of the git program in the Jenkins global configuration screen. That might satisfy the default Git installation finding method and avoid the null pointer exception. Mark Waite
