在使用Ant成功使用PMD多年后,我现在正试图让PMD在Maven中工作,但没有成功。
为了说明我的问题,我创建了一个简单的Maven系统(基于Maven教程“my-app”hello world程序)。它的不同之处仅在于包含一行代码,它应该使用基本规则集触发PMD错误:
Boolean bar = new Boolean("true");
当我从命令行运行PMD时,会显示代码中的问题:
run.sh pmd -d src/main/java -f text -R rulesets/java/basic.xml -language java
maven-pmd-example/src/main/java/com/mycompany/app/App.java:11 Avoid instantiating Boolean objects; reference Boolean.TRUE or Boolean.FALSE or call Boolean.valueOf() instead.
但是,当我从Maven中运行pmd时,代码中的问题没有显示出来:
-> mvn pmd:check

我已将此示例系统上传到GitHub,因此您可以查看整个示例系统(如果您愿意,可以下载/播放):
答案 0 :(得分:1)
这是因为您已将minimumPriority
设置为0,这将有效阻止PMD评估任何规则(有关优先级的讨论,请参阅to this SO question。)
请提供PMD插件目标文档的refer to this section以获取更多信息。
我建议修改配置以将minimumPriority
设置为2,这样就可以使BooleanInstantiation
的构建失败。
希望这有帮助!
