2026-??-?? - 7.27.0-SNAPSHOT

The PMD team is pleased to announce PMD 7.27.0-SNAPSHOT.

This is a minor release.

🚀️ New and noteworthy

Updated Apex Support

The Apex language support has been bumped to version 67.0 (Summer ‘26). It supports the new Multiline String literals.

Kotlin type-aware analysis

Kotlin now supports type-aware analysis via the auxClasspath language property (see #6677). Resolved type names, return types, and annotation FQNs are available through KotlinNodeTypeData for use in Java-based rules.

Note: Type data is not yet accessible in XPath rules or the PMD Rule Designer. This will be added in the next version.

🌟️ New and Changed Rules

Renamed Rules

The rule InstantiableUtilityClass (Java Design) was renamed from UseUtilityClass to better reflect the problem. The old name still works but is deprecated.

🚨️ API Changes

Deprecations

core
- PMDConfiguration#getClassLoader and PMDConfiguration#setClassLoader are deprecated. Use prependAuxClasspath or setAuxClasspath to configure the auxClasspath for analyzing Java code.
  Note: In order to read back the currently configured auxClasspath, use getAuxClasspath and not the deprecated getClassLoader() anymore.
  Using ClassLoaders directly is discouraged, as it is unclear, if and when the ClassLoaders should be closed to release their resources. By just configuring the auxClasspath, PMD internally can deal with that.

Experimental API

kotlin
- KotlinNodeTypeData: Provides the initial API to access type information on Kotlin AST nodes. It’s part of the new Kotlin type-aware analysis.
