[MDEP-895] dependency:sources fails for multi-module project
Gerd Aschemann opened MDEP-895 and commented
When executing mvn dependency:sources on a multi-module project it fails to retrieve sources for the modules themselves (which is not necessary as the source code is provided locally already):

This is similar to the behaviour of MDEP-409.
A test and PR is already prepared: https://github.com/jmle/maven-dependency-plugin/tree/fix-sources-multimodule
Affects: 3.6.1

The applied change changes the semantics and contradicts the actual resolve operation. The goal is poorly named. It should have been resolve-sources. We will deprecate this one and create successor.

I think the message is fine. However, it seems reasonable to make
mvnw -N org.apache.maven.plugins:maven-dependency-plugin:3.1.2:get -Dartifact=org.joda:joda-beans:jar:2.8.1
work as well. The other syntax (no :jar) should also work too, of course.
