Tips for speeding up build time on Linux using ANT, Javacc, JUnit, and compiling Java classes

Question

We have a large code base that takes about 12 minutes on the developer's machines to automatically generate some Java 5 classes using JavaCC, and then compiles all the classes, and also starts unit testing.

A project consists of several projects that can be created by teams, but we strive for complete assembly in less than 10 minutes.

What are some tips for reducing assembly time?

thanks
