31-January-2025 - 7.10.0

The PMD team is pleased to announce PMD 7.10.0.

This is a minor release.

🚀 New and noteworthy

🚀 New: Java 24 Support

This release of PMD brings support for Java 24. There are no new standard language features, but a couple of preview language features:

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 24-preview:

export PMD_JAVA_OPTS=--enable-preview
pmd check --use-version java-24-preview ...

Note: Support for Java 22 preview language features have been removed. The version “22-preview” is no longer available.

New GPG Release Signing Key

Since January 2025, we switched the GPG Key we use for signing releases in Maven Central to be A0B5CA1A4E086838. The full fingerprint is 2EFA 55D0 785C 31F9 56F2 F87E A0B5 CA1A 4E08 6838.

This step was necessary, as the passphrase of the old key has been compromised and therefore the key is not safe to use anymore. While the key itself is not compromised as far as we know, we still decided to generate a new key, just to be safe. As until now (January 2025) we are not aware, that the key actually has been misused. The previous releases of PMD in Maven Central can still be considered untampered, as Maven Central is read-only.

This unexpected issue was discovered while checking Reproducible Builds by a third party.

The security advisory about the compromised passphrase is tracked as GHSA-88m4-h43f-wx84 and CVE-2025-23215.

Updated PMD Designer

This PMD release ships a new version of the pmd-designer. For the changes, see PMD Designer Changelog (7.10.0).

🌟 New and changed rules

New Rules

  • The new Java rule ExhaustiveSwitchHasDefault finds switch statements and expressions, that cover already all cases but still have a default case. This default case is unnecessary and prevents getting compiler errors when e.g. new enum constants are added without extending the switch.

🐛 Fixed Issues

  • apex
    • #5388: [apex] Parse error with time literal in SOQL query
    • #5456: [apex] Issue with java dependency apex-parser-4.3.1 but apex-parser-4.3.0 works
  • apex-security
    • #3158: [apex] ApexSuggestUsingNamedCred false positive with Named Credential merge fields

🚨 API Changes

Removed Experimental API

  • pmd-java
    • net.sourceforge.pmd.lang.java.ast.ASTTemplate, net.sourceforge.pmd.lang.java.ast.ASTTemplateExpression, net.sourceforge.pmd.lang.java.ast.ASTTemplateFragment: These nodes were introduced with Java 21 and 22 Preview to support String Templates. However, the String Template preview feature was not finalized and has been removed from Java for now. We now cleaned up the PMD implementation of it.
