Romain Manni-Bucau commented on MSOURCES-143: --------------------------------------------- [~rvesse] yes, if you check the output you see that attach-sources is done twice, one being explicit in the project pom, dropping it solves it and still enable to complete the release "as expected". (side note: for the setup using a local repo is easier than your github where we don't have perms - for good - so switched to <connection>scm:git:file:///tmp/repo</connection> to test). I think it is cause of default binding of source plugin and you don't override it but append your execution. Agree a help mojo could simplify the visualisation of the flows/pipelines too. > 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.
