Project "PMD" has released the new version

From the site...

PMD scans Java source code and looks for potential problems like:

• Empty try/catch/finally/switch blocks


• Unused local variables, parameters and private methods


• Empty if/while statements


• Overcomplicated expressions - unnecessary if statements, for loops that could be while loops


• Classes with high Cyclomatic Complexity measurements

PMD has plugins for JDeveloper, Eclipse, JEdit, JBuilder, Omnicore's CodeGuide, NetBeans/Sun ONE Studio, IntelliJ IDEA, TextPad, Maven, Ant, Gel, JCreator, and Emacs. You can download everything from here.
