Jenkins 2.204.5
Git Plugin 4.1.1
Once in a while, at least several times a week, the name of the Git executable ends up being unset and the Git plugin calls ` init` (whitespace) instead of `git init`.
We use a custom installer for git and it works and install just fine and even with jobs with multiple parallel stages, only one stage hits the bug, randomly. So configuration on our side is just fine but we suspect that there is a bug in the codebase where the variable holding the git executable name can get invalidated, at the stage level.
