PMD Release Notes

26-April-2024 - 7.1.0-SNAPSHOT

The PMD team is pleased to announce PMD 7.1.0-SNAPSHOT.

This is a minor release.

🚀 New and noteworthy

✨ New rules

• The new Java rule UnnecessaryVarargsArrayCreation reports explicit array creation when a varargs is expected. This is more heavy to read and could be simplified.

🌟 Rule Changes

• JUnitTestsShouldIncludeAssert and JUnitTestContainsTooManyAsserts have a new property named extraAssertMethodNames. With this property, you can configure which additional static methods should be considered as valid verification methods. This allows to use custom mocking or assertion libraries.
