    <description>
        The default ruleset used by the Maven PMD Plugin, when no other ruleset is specified.
        It contains the rules of the old (pre PMD 6.0.0) rulesets java-basic, java-empty, java-imports,
        java-unnecessary, java-unusedcode.

        This ruleset might be used as a starting point for an own customized ruleset [0].
