Just configured Hudson to build my project. It was easy. After configuring Mercurial and Maven it was nothing more than triggering the build. I found an extremely helpful tool for maven projects, it is m2eclipse. It allows you to create Maven projects within Eclipse which is nice but for me the killer feature was the pom.xml editor!
Looking up dependencies is easy! Just add a dependency and m2eclipse will provide you a search. Start typing the dependency name and it will show you the results of its search. Select what you want with correct scope and you are done.
Now, time to get back to test-drive some features to my home experiment!
