for example i am working with the Multiple-SCM's plugin which can add multiple GitSCM actions.
BuildData gitBuildData = build.getAction(BuildData.class);
'Gets the action (first instance to be found) of a specified type that
contributed to this build.'
So...for each job run i only want the newest (or the repository that triggered the build) .
But for that to work, the actions would need to be sorted by date created in Descending order.
