New Supported Languages:

  • CPD supports now Swift (see PR#33).

Feature Request and Improvements:

  • A JSON-renderer for PMD which is compatible with CodeClimate. See PR#83.

Modified Rules:

  • java-design/UseVargs: public static void main method is ignored now and so are methods, that are annotated with Override. See PR#79.

CLI Changes:

  • CPD: If a complete filename is specified, the language dependent filename filter is not applied. This allows to scan files, that are not using the standard file extension. If a directory is specified, the filename filter is still applied and only those files with the correct file extension of the language are scanned.
