Properties in cases where you want to easily vary things from the command
line; configuration where you want to lock it down.  Obviously the other
considerations (like profiles) are worth considering as well.

I've found just for reducing the boilerplate that I err on the side of
properties for simple "no, dammit, I don't want source to be 1.3"
settings--if I'm not concerned with multiple executions, etc.

One thing I've never been clear on is the override mechanisms: if I have a
super pom with <properties> in it, a sub pom with <properties> in it that
has some overrides in it, and a command line property, I would hope that
the command line stomps on both the sub and super pom property values in
question.  I haven't sat down and rigorously tested this.

Best,
Laird
