Subject Re: Multiple dependencies with the same id but different types
Date Thu, 02 Sep 2004 00:07:00 GMT
If no one can actually fix your problem, you can always build the 
adapter jar in one project and package it into the rar in another, with 
slightly different names.  I would definitely prefer that someone 
figure out how to have multiple dependencies such as you ask for.
