在添加 PMD 的自定义规则集时，maven 产生错误 - net.sourceforge.pmd.RuleSetNotFoundException: Can't find resource rulesets/comments.xml.Make sure the resource is a valid file or URL or is on the CLASSPATH.
对于其他规则集，如基本、命名等，它不会给出任何错误。但是当我添加新规则集时，它会产生错误。我也尝试过<rule ref="rulesets/java/comments.xml/CommentRequired"/>，但它也给出了同样的错误。comments.xml 已在 pmd-5.0.2.jar 文件中可用。
