This is just a cut down version of a much larger project of which I use Postgres with Glassfish for deployment testing (as Derby database doesn't work with jBPM). So I deliberately force that check that Java 1.6 is not run, meaning the right bracket is correct for a less than and not equal to condition. Also cos this currently doesn't work, I wanted to ensure people were running Java5 which is more widely supported than Java6 to rule out any issues there. I could be wrong there though :) Checkout this link for more info: http://docs.codehaus.org/display/MAVEN/Dependency+Mediation+and+Conflict+... As for your depenendency error, it's cos the project has not successfully compiled that project and so has not produced that artifact. You need to first run it without tests: mvn -Dmaven.test.skip=true clean install That will ensure all projects are built and their artifacts available in your local repository.
