Hi Jarod,
I can't offer any specific advice on the -sourcepath issue. However you
should be aware of something about Maven: Maven is NOT as flexible as
ant. And that is deliberate.
Ant is pretty much a Turing-complete programming language that can do
anything. But the disadvantage is that because it can do anything,
people make it do some very weird and unmaintainable things. Your
current setup sounds like it might well fall into that category.
It is precisely because Maven does *not* support every weird setup that
its builds remain more maintainable and comprehensible.
So if you are moving to Maven, you might find that you are forced to
clean up your project structures before Maven will work for you. Maven
is somewhat tweakable but if you don't want to follow its approach at
all, then it is better to stay with Ant (maybe using the maven ant tasks
for dependency resolution, or using ant+ivy).
This thing about compiling other module's code for them sounds really
un-mavenish. How on earth are you going to properly define the module's
dependencies when that is going on?
Regards,
Simon
