Eclipse build fails (locally) as well as from user (recent) reports. I got this when just tried mvn clean

Yeah, need to upgrade the builds to the newest versions..
Maven 3.1 has a big change of Sonatype Aether to Eclipse Aether: https://cwiki.apache.org/confluence/display/MAVEN/AetherClassNotFound
Because of this change, a number of plug-ins had to be upgraded as well. This particular error comes from Tycho, which needs to be upgraded to version >= 0.18.1 to be compatible with Maven 3.1: http://wiki.eclipse.org/Tycho/Release_Notes/0.18
As a workaround (before I get around to doing this), try using Maven 3, not Maven 3.1.
