26-November-2022 - 6.52.0-SNAPSHOT

The PMD team is pleased to announce PMD 6.52.0-SNAPSHOT.

This is a minor release.

New and noteworthy

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.

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 aleternative.

Deprecated API

The following APIs have been marked as deprecated for removal in PMD 7:
