[ANN] Apache Maven 3.0-alpha-3 Released

The Maven team is pleased to announce the release of Apache Maven 
3.0-alpha-3.

Maven is a project comprehension and build tool, designed to simplify
the process of maintaining a healthy development lifecycle for your
project. You can read more here:

   http://maven.apache.org/

Downloads of source and binary distributions are already available on 
the central Maven repository and various Apache download mirrors and 
will be listed soon in our download section once the updated site gets 
synced to the live server:

   http://maven.apache.org/download.html

A major goal of Maven 3.0 is to be compatible with existing plugins and 
projects designed for Maven 2.x. Users interested in testing this alpha 
release should have a glance at the compatibility notes for known 
differences between Maven 3.0 and Maven 2.x:

   http://cwiki.apache.org/MAVEN/maven-3x-compatibility-notes.html

As of this writing, we already know about one regression in Maven 
3.0-alpha-3 that prevents the forced update of SNAPSHOT POMs via the 
command line flag -U. If you encounter unexpected problems while using 
Maven 3.0-alpha-3, please feel free to contact us via the Maven 
developer list:
