New rules

<rule ref="category/java/design.xml/InvalidJavaBean"/>

Renamed rules

The property prefix has been deprecated, since in a serializable class all fields have to be serializable regardless of the name.

Modified rules

  • The rule ClassNamingConventions has a new property testClassPattern, which is applied to test classes. By default, test classes should end with the suffix "Test". Test classes are top-level classes, that either inherit from JUnit 3 TestCase or have at least one method annotated with the Test annotations from JUnit4/5 or TestNG.

  • The property ignoredAnnotations of rule ImmutableField has been deprecated and doesn't have any effect anymore. Since PMD 6.47.0, the rule only considers fields, that are initialized once and never changed. If the field is just declared but never explicitly initialized, it won't be reported. That's the typical case when a framework sets the field value by reflection. Therefore, the property is not needed anymore. If there is a special case where this rule misidentifies fields as immutable, then the rule should be suppressed for these fields explicitly.

API Changes

PMD CLI

  • PMD now supports a new --use-version flag, which receives a language-version pair (such as java-8 or apex-54). This supersedes the usage of -language / -l and -version / -v, allowing for multiple versions to be set in a single run. PMD 7 will completely remove support for -language and -version in favor of this new flag.

  • Support for -V is being deprecated in favor of --verbose in preparation for PMD 7. In PMD 7, -v will enable verbose mode and -V will show the PMD version for consistency with most Unix/Linux tools.

  • Support for -min is being deprecated in favor of --minimum-priority for consistency with most Unix/Linux tools, where -min would be equivalent to -m -i -n.

CPD CLI

  • CPD now supports using -d or --dir as an alias to --files, in favor of consistency with PMD. PMD 7 will remove support for --files in favor of these new flags.

Linux run.sh parameters

  • Using run.sh cpdgui will now warn about it being deprecated. Use run.sh cpd-gui instead.

  • The old designer (run.sh designerold) is completely deprecated and will be removed in PMD 7. Switch to the new JavaFX designer: run.sh designer.

  • The old visual AST viewer (run.sh bgastviewer) is completely deprecated and will be removed in PMD 7. Switch to the new JavaFX designer: run.sh designer for a visual tool, or use run.sh ast-dump for a text-based alternative.
