If you're a Maven user and like Eclipse, you might want to checkout the new Maven Integration Plugin for Eclipse 0.9.0. Euxx has a couple blog posts talking about the new features - looks like pretty cool stuff to me.
- Indexing Maven repositories - for offline browsing of repositories.
- Making a good use of Maven metadata - materializing projects from dependencies.
The second feature is especially cool. If your dependencies supply SCM information - you can import the project from its source control system. Maven may have warts, but it also has incredible potential.
