We are pleased to announce the Maven PMD Plugin 1.7 release! 

http://maven.apache.org/maven-1.x/plugins/pmd/

The Maven PMD plugin is a plugin that wraps the PMD framework 
(http://pmd.sourceforge.net). PMD is a source checking framework that works by 
scanning Java source code and looks for potential problems like: unused local 
variables, empty catch blocks, unused parameters, empty 'if' statements, etc. 

===============================================================================

Changes in this version include:

  New Features:

o Added ability to check test sources. Fixes MPPMD-14. 

  Changes:

o Upgrade to pmd-3.2. Fixes MPPMD-15.
