New and noteworthy

New Rules

  • The new Apex rule AvoidNonExistentAnnotations (apex-errorprone) detects usages non-officially supported annotations. Apex supported non existent annotations for legacy reasons. In the future, use of such non-existent annotations could result in broken Apex code that will not compile. A full list of supported annotations can be found here

Modified Rules

  • The Java rule UnnecessaryModifier (java-codestyle) now detects enum constrcutors with explicit private modifier. The rule now produces better error messages letting you know exactly which modifiers are redundant at each declaration.

API Changes

  • The utility class net.sourceforge.pmd.lang.java.ast.CommentUtil has been deprecated and will be removed with PMD 7.0.0. Its methods have been intended to parse javadoc tags. A more useful solution will be added around the AST node FormalComment, which contains as children JavadocElement nodes, which in turn provide access to the JavadocTag.

    All comment AST nodes (FormalComment, MultiLineComment, SingleLineComment) have a new method getFilteredComment() which provide access to the comment text without the leading /* markers.

  • The method AbstractCommentRule.tagsIndicesIn() has been deprecated and will be removed with PMD 7.0.0. It is not very useful, since it doesn’t extract the information in a useful way. You would still need check, which tags have been found, and with which data they might be accompanied.
