PMD + Maven + JAVA錯誤::無法找到資源rulesets / comments.xml。 確保資源是有效的文件或URL，或者位於CLASSPATH上

Question

在添加PMD的自定義規則集時，maven產生錯誤 - 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 。

對於其他規則集，如基本，命名等，它沒有給出任何錯誤。但是當我添加新的規則集時，它產生了錯誤。 我也試過<rule ref="rulesets/java/comments.xml/CommentRequired"/>但它也給出了同樣的錯誤。 comments.xml已在pmd-5.0.2.jar文件中提供。

Answer 1

該插件只能理解絕對路徑。 嘗試絕對路徑，它應該工作。 請參閱文檔。

為了使其獨立於本地文件系統布局，請使用${basedir}來引用本地路徑。

Answer 2

它必須是“rulesets / java / comments.xml”而不是“rulesets / comments.xml”。

我懷疑是，你從過時的文檔的某些部分中選擇了“rulesets / comments.xml”，或者在發布之前沒有經過測試。
