Maven + Emacs + JDEE = coding bliss

If you use Emacs/JDEE and Maven, you may want to look at my pom-parser.el, which lets you refer to information in your POM from your JDEE project files. The code is loosely based on Ole Arndt's work, but works with Maven 2. It delegates much of the work to Maven itself and the help and dependency plugins.
