maven constantly rebuilding everything

[EJ Ciramella]

I've just noticed kinda a little delemma here.  From build to build,
when NOTHING has changed inside module "A", I can see that its still
rebuilding the jar for this particular module.
 
Is there any reason this should be happening?  Like say it is set to
build a "snapshot" version?  I think it would notice that the source
directory doesn't contain any changes and not build.
 
Any help/suggestions would be greatly appreciated.
