One pom -> one artifact
to create two artifacts, use a multi-module project.
Anything else is a hack that will end in tears... and it's far far far
quicker to just do it the right way... if you don't like the right way
might I suggest ANT or any other number of procedural build tools that
you can bend to your will and then 3 years later when you come back to
the project you can spend five weeks tearing out your hair trying to
figure out what exactly you did and why ;-)
