The PMD team is pleased to announce PMD 6.55.0.
This is a minor release.
This release is the last planned release of PMD 6. The first version 6.0.0 was released in December 2017. Over the course of more than 5 years we published almost every month a new minor version of PMD 6 with new features and improvements.
Already in November 2018 we started in parallel the development of the next major version 7.0.0, and we are now in the process of finalizing the scope of the major version. We want to release a couple of release candidates before publishing the final version 7.0.0.
We plan to release 7.0.0-rc1 soon. You can see the progress in PMD 7 Tracking Issue #3898.
This release of PMD brings support for Java 20. There are no new standard language features.
PMD supports JEP 433: Pattern Matching for switch (Fourth Preview) and JEP 432: Record Patterns (Second Preview) as preview language features.
In order to analyze a project with PMD that uses these language features,
you’ll need to enable it via the environment variable PMD_JAVA_OPTS
and select the new language
version 20-preview
:
export PMD_JAVA_OPTS=--enable-preview
./run.sh pmd --use-version java-20-preview ...
Thanks to the contribution from Paul Guyot PMD now has CPD support for T-SQL (Transact-SQL).
Being based on a proper Antlr grammar, CPD can:
