Is there any progress on this issue?
It would be really really great if there was a way to tell if archiveArtifacts worked or not! I have a job that builds a lot of stuff and has ~750 steps. It's totally impossible to find out where the pipeline failed in case archiveArtifacts failed, because every step is green and there's no output at all that points me to the correct place.
My approach is now more a Poor Man's Debugger than a solution: I put masses of printlns in it which give me the current build result. But this doesn't necessarily mean that the error happened at that specific place if you build stuff in parallel.
IMHO, archiveArtifacts should at least print out the amount of files it included. Also a return value containing the files or the number of files would be great. But instead of failing silently, I'd prefer an Exception.
