The Symptom:
When using an enterprise GHE that is running slow (or I imagine, with a very fast jenkins instance, maybe even on production GH), a check for a Jenkinsfile in the branch events will say that one was not found, even though there is a Jenkinsfile in the PR's origin branch, and in the target branch. This seems to happen if you "slam" GH by creating a commit, branch, and PR all in one go (which people do with automated commits).
What I think is the cause:
As far as I can tell, GitHubSCMProbe is relying on the contents API to determine if a new branch or PR has a Jenkinsfile. When building merge PRs, it uses the merge refs with the contents API, but the merge refs aren't actually ready yet when GH sends out its webhooks. To prove this, I spun up a ruby sinatra app that listens for a PR webhook and immediately calls back to GH with the contents API. This reliably fails to find a ref (returns "No commit found for the ref"), unless you put a short sleep between when it receives the webhook, and when it calls out for content. You can find that here: https://github.com/SpencerMalone/test-repo if you want to play with it yourself.
This is probably something that GH needs to fix, so I've sent them a support ticket, but just incase they are unable to, or in case it takes an exceedingly long time, I've opened this.
I think in cases where we get a ref not found from the contents API while responding to branch events, there should be a short delay + retry.
