PMD 5.4.1

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:

# Feature Request and Improvements:
* CPD: New command line parameter --ignore-usings: Ignore using directives in C# when comparing text.
# Modified Rules:
* java-comments/CommentRequired: New property serialVersionUIDCommentRequired which controls the comment requirements for serialVersionUID fields. By default, no comment is required for this field.
# Pull Requests:
* Added option to exclude C# using directives from CPD analysis
* Added capability in Java and JSP parser for tracking tokens.
* Fix rendering CommentDefaultAccessModifier description as code
* RuleSetFactory Performance Enhancement
