Krzys H. added a comment - 2017-06-23 13:38 I just had the exact same thing happen to me. I'm guessing the reason is that the pull request #555 in your repository is pointing to a branch or repo that has been removed (noted as "unknown repository" on GitHub page) I'm including my logs below, although they look quite similar. In my case this bug caused the whole project to be removed in Jenkins along with all other branches, possibly because this pull request was the first thing that was checked.
