If job "B" is downstream of job "A" and both draw from the same git repository, how can one ensure that the build of B triggered by a build of A uses the same commit, even if new commits have been made to the repository while "A" was building?
The answer to this post suggests using the copy-artifact plugin, but it seems like there ought to be an easier way to just instruct job "B" to "use this exact commit hash for this build."
