      We have a few jobs whos git repos have branches created and PRs raised against multiple upstream branches, frequently. All forks and upstream repos are accessible to the Jenkins instance(s). Our configuration uses origin/* as the branch specifier because the job needs to be able to build all pull-requests that are raised against the upstream repo. Once in a while, a job would fail with this message:

      Upon investigation, the SHA that Jenkins was attempting to check out was either in a branch of a PR, or just a branch that was deleted, or a commit in a separate fork.

      The issue overall seems to be that the SCM plugin is trying to checkout SHAs that are not in the origin remote (i.e.: the upstream repo) and instead the SHA of some other fork. This is strange since the branch specifier is origin/, not */*
