Rob Vesse commented on MSOURCES-143:
------------------------------------
I don't understand the lack of urgency from the Maven Source Plugin developers
here.
You've got lots of examples here, and on related issues such as MSOURCES-140
where this change in your plugins behaviour is breaking peoples longstanding
build processes. I've got a whole bunch of projects, some with parent POMs,
some completely standalone, where upgrading to 3.3.0 breaks the ability to do a
Maven release, and most frustratingly not until the {{release:perform }} stage
forcing a {{release:rollback}}.
I've spent far too much time staring at {{mvn help:effective-pom}} output to
try to understand why/how I'm invoking the source plugin multiple times because
as far as I can see I am not yet I hit the error unless I rollback to 3.3.0
