The app pom introduces A:1.0-RELEASE, and this artifact A has transitive dependency B:0.12.0-SNAPSHOT. In app pom, we manage B as version 0.13.0-RELEASE.
When the pmd:3.15.0 and above is being executed, it will resolve dependencies, and somehow the B:0.12.0-SNAPSHOT is resolved as a dependency instead of B:0.13.0-RELEASE.
This is not only downloading wrong version, but also means lots of transitive dependencies with unmanaged version will be always downloaded (if not in cache) causing build slowness. Especially when we are using BF option: -Daether.dependencyCollector.impl=bf, this algorithm will skip downloading poms of for conflict losers, but maven-pmd-plugin (having this bug) again downloads those skipped ones.
