PMD Release Notes

Edit me

??-October-2019 - 6.19.0

The PMD team is pleased to announce PMD 6.19.0.

This is a minor release.

New and noteworthy

Modified Rules

• The Java rules InvalidSlf4jMessageFormat and MoreThanOneLogger (java-errorprone) now both support Log4j2.

• The Java rule LawOfDemeter (java-design) ignores now also Builders, that are not assigned to a local variable, but just directly used within a method call chain. The method, that creates the builder needs to end with “Builder”, e.g. newBuilder() or initBuilder() works. This change fixes a couple of false positives.

• The Java rule DataflowAnomalyAnalysis (java-errorprone) doesn’t check for UR anomalies (undefined and then referenced) anymore. These checks were all false-positives, since actual UR occurrences would lead to compile errors.
