Last week, I attended a talk by Jason van Zyl on Comprehensive Project Intelligence. This talk contained a good overview of some Maven goodies that Jason's company has been working on - namely better repository management (Nexus), better Eclipse support (m2eclipse) and improving an awesome CI server (we use Hudson heavily at LinkedIn).
It looks like Jason is going to be doing a similar session in a full-day format at ApacheCon next week. The good news is it's free, the bad news is you have to be in New Orleans. Hopefully Jason and team will post their slides from this event and we can all learn how to use Maven more effectively.
In other Maven-related news, I hope to complete AppFuse 2.1 around the same time as Spring 3.0 (early next year). As part of that release, I hope to start using Nexus for AppFuse's repository as well as restructure its archetypes to allow using m2eclipse (with WTP) more effectively.
