4.0.0 net.sourceforge.pmd pmd 5.2.3 pom PMD org.sonatype.oss oss-parent 7 PMD scans Java source code and looks for potential problems like:

Possible bugs - empty try/catch/finally/switch statements
Dead code - unused local variables, parameters and private methods
Suboptimal code - wasteful String/StringBuffer usage
Overcomplicated expressions - unnecessary if statements, for loops that could be while loops
Duplicate code - copied/pasted code means copied/pasted bugs

You can download everything from here, and you can get an overview of all the rules at the rulesets index page.

PMD is integrated with JDeveloper, Eclipse, JEdit, JBuilder, BlueJ, CodeGuide, NetBeans/Sun Java Studio Enterprise/Creator, IntelliJ IDEA, TextPad, Maven, Ant, Gel, JCreator, and Emacs.
