This job fails in the current stripped down jenkins env and probably needs to build in a container:

jenkins update-cmirror job broken
This appeared to be a quick and easy fix but it was actually a multi-hour headache as it turns out that the jenkins pipeline git step is completely incapable of checking out a tag as opposed to a branch.
A brief audit was also done of periodic jobs that should be running a regular basis but were not being triggered.
