PMD 5.7.0

PMD is a source code analyzer. It finds common programming flaws like unused variables, empty catch blocks, unnecessary object creation, and so forth. It supports Java, JavaScript, XML, XSL.

Available Plugins include:

• Maven PMD.
• Eclipse.
• NetBeans.
• JBuilder.
• JDeveloper.
• IntelliJ IDEA.

PMD additionally includes CPD, the copy-paste-detector. CPD finds duplicated code in Java, C, C++, C#, PHP, Ruby, Fortran, JavaScript, PLSQL, Apache Velocity, Scala, Objective C, Matlab, Python, Go.

Modified Rules:
The rule “FieldDeclarationsShouldBeAtStartOfClass” of the java-design ruleset has a new property ignoreInterfaceDeclarations. Setting this property to true ignores interface declarations, that precede fields.
Renderers:
Added the ‘empty’ renderer which will write nothing. Does not affect other behaviors, for example the command line PMD exit status will still indicate whether violations were found.
