Hi All,

For good or bad, I ended learning more than I care about Maven being the
release manager for several Apache Commons components.

Our rule in Commons is that when you change a package name, you must change
the Maven artifact id.

My suggestion is to do this in your POM:


Depending on your philosophy, you could also re-publish the Maven artifacts
for 2.0.1. But this is usually considered bad form because the POM needs to
change and you would then have 2 2.0.1 version with different pom.xml in
your sources jar.
