I started to migrate some of our ASG projects from Maven 1 to Maven 2. The new Maven version finally provides everything I expected from the first version, especially dependency trees. The IBiblio repository is still a mess. Therefore you might need to deploy some needed libraries manually to your own (company ?) Maven2 repository:

In ASG, my repository login is not the same as my local user name. Therefore, I first needed to patch MAVEN2_HOME/conf/preferences.xml in order to add the username and password for the remote access (see here). The name/password pair is referenced by the server id, which you can provide in the deployment command:
