I'm currently implementing one project with M2 but finding the dependancy gathering to be a little awkward. For example, I want to use Spring 1.2.6 and Hibernate 3.1 and I state that in my pom.xml. However, it will grab Hibernate 3.0.5 and Hibernate 2.1.7 as those are stated as requirements for Spring and doesn't "realise" that I'm already grabbing Hibernate.
