I have two things:

1) Is there a reason you don't just keep the library project in your 
workspace and have the other projects depend directly on it (instead of 
using a JAR in the other projects)? With a direct dependency like that 
and Build Automatically enabled (it is by default), everything "just works."

2) If #1 is not an option for some reason, it is pretty easy to write a 
custom builder using Ant. For some help getting started, see

Hope this helps,
Eric
