🚀 New and noteworthy

🚀 New: Java 25 Support

This release of PMD brings support for Java 25.

There are the following new standard language features:

• JEP 511: Module Import Declarations
• JEP 512: Compact Source Files and Instance Main Methods
• JEP 513: Flexible Constructor Bodies

And one preview language feature:

• JEP 507: Primitive Types in Patterns, instanceof, and switch (Third Preview)

In order to analyze a project with PMD that uses these preview language features, you’ll need to enable it via the environment variable PMD_JAVA_OPTS and select the new language version 25-preview:

export PMD_JAVA_OPTS=--enable-preview
pmd check --use-version java-25-preview ...

Note: Support for Java 23 preview language features have been removed. The version “23-preview” is no longer available.

New: CPD support for CSS

CPD now supports CSS (Cascading Style Sheets), a language for describing the rendering of structured documents (such as HTML) on screen, on paper etc.
It is shipped with the new module pmd-css.

✨ New Rules

• Two new rules have been added to Java’s Error Prone category: ReplaceJavaUtilCalendar and ReplaceJavaUtilDate. These rules help to migrate away from old Java APIs around java.util.Calendar and java.util.Date. It is recommended to use the modern java.time API instead, which is available since Java 8.
