Ben Tatham commented on MNG-2363:
---------------------------------

I have the same issue, but not using modules.  

This is the critical point:
"Instead, during a multi-project build the profile is either on or off 
depending on whether the file exists relative to the aggregator pom. The 
decision is made once."

I want a parent pom to define some plugin executions (like xdoclet, jspc, etc), 
so I can reuse those plugin configurations in all my other projects that need 
these tools.  Of course, that parent project doesn't have servlets/tags/jsps to 
compile, so I have to use a profile to define them so that I can actually 
install the pom project itself.  But I don't want to have to use a command line 
property to turn it on...my tests rely on those plugins running.
