Hi Uwe, Sorry about the late reply.
this is because a default Windows installation has no git installed. As > the recent build system removed jgit (why????) it won't work anymore. I Ok, I'll revert the jgit implementation then. The reason to remove it was that native git has stable support to get the status in a fairly easy-to-parse format - this allows us to use newer git features, which jgit implements much later (worktrees are a good example). > am not happy about that as it makes our build system again rely on more > native tools which are provided by Java. The jgit implementation was > working well, so why remove it? Jenkins itsself uses jgit, too, so the > build node does not need git. > jgit didn't work with worktrees for a loong time. I think it does have some support for it now though. I hear you, I'll revert to jgit asap, sorry for the problem. #14785. D.
