What I tried

https://stackoverflow.com/a/2033299/1839360 Added a dependency for pmd-java - it did not work. I tried both versions https://mvnrepository.com/artifact/net.sourceforge.pmd/pmd-java/6.21.0 https://mvnrepository.com/artifact/net.sourceforge.pmd/pmd-java/6.23.0

With the latest version, there is an error

Can be realted, but I am not sure. It is for older version Java https://stackoverflow.com/questions/2033217/how-to-make-maven-pmd-plugin-support-the-latest-pmd-release — Yan Khonski, Apr 24 '20 at 21:52
Support for JDK 14 was formally announced with [PMD 6.22.0 released on March 12](https://github.com/pmd/pmd/releases/tag/pmd_releases%2F6.22.0#java-14-support): _"This release of PMD brings support for Java 14. PMD can parse Switch Expressions, which have been promoted to be a standard language feature of Java. PMD also parses Text Blocks as String literals, which is still a preview language feature in Java 14. The new Pattern Matching for instanceof can be used as well as Records."_ — skomisa, Apr 25 '20 at 01:42

Java 14 is only supported with PMD 6.22.0+. What you've configured now, is described here: https://maven.apache.org/plugins/maven-pmd-plugin/examples/upgrading-PMD-at-runtime.html The next maven-pmd-plugin will use a newer PMD version (see https://issues.apache.org/jira/browse/MPMD-302) — adangel, Apr 25 '20 at 09:00
Agree, I saw this page through related searches. However, it does not say anything about Java 14. After putting my answer here, other people can google and find it here. Feel free to post your answer with more details. — Yan Khonski, Apr 25 '20 at 09:07
Can confirm, I Googled this issue and found this. It worked, thanks! I didn't specify `6.23.0`, but I specified a range of `[6.22.0,)`, but basically the same thing you did. — Austin Brown, Nov 04 '20 at 00:07
