Gary D. Gregory commented on MSOURCES-143: ------------------------------------------ Hi [~sjaranowski] I am sorry but I still don't get it. What does the SPDX plugin's PR (removing something that happens at verify?) have to do with creating source and test source jars? I just want to build source jars and I don't need to understand what SPDX does beyond creating it's own custom files. Are you saying that SPDX, as part of it's own execution, causes the source and test source jars to be generated, and that's indeed the issue? Hi [~romain.manni-bucau] "whatever will make the error case no more hit avoiding rebuild of the same mvn mojo execution" So do whatever fixes the problem? Great advice. Sorry for being sarcastic but this is the level of Maven Magic that I find frustrating. I not sure if what I am trying to do is unusual or a stretch or what, but I'm looking for specific help on what to do here. > Can't create a source and test jar in Commons using commons-parent > ------------------------------------------------------------------ > > Key: MSOURCES-143 > URL: https://issues.apache.org/jira/browse/MSOURCES-143 > Project: Maven Source Plugin > Issue Type: Bug > Affects Versions: 3.3.0 > Reporter: Gary D.
