Installing Sources In Maven

A friend of mine was asking how to actually install the sources of a maven project to a repository. Downloading the sources of other dependencies is easy enough - all that needs to happen is the addition of the -DdownloadSources=true argument to your mvn goals. But how do you allow other projects who depend on your artifacts to do the same. The answer: Maven's Source Plugin. Essentially, all you need to do is

mvn source:jar install

for your projects source and

mvn source:test-jar install

for your test source of your project and viola! The sources are now in the repository.
