【问题讨论】：

"干净" != "干净"
错误信息试图告诉你一些事情。不过与其试图理解，不如截个图上传到这里？
@azurefrog 你能解释一下吗
"Clean" 和 "clean" 不是同一个字符串。一个是 Maven 中的有效生命周期阶段，另一个不是。我不确定如何更清楚。
谢谢@azurefrog。我解决了这个问题，我的 Maven 项目在 jenkins 中成功执行。

标签： maven jenkins

【解决方案1】：

正如@azurefrog 通过评论所解释的那样，"Clean" != "clean"、Jenkins、Maven 和 Linux 都区分大小写，这就是为什么“干净”不匹配“可用生命周期”之一阶段”，因此错误消息：

Unknown lifecycle phase "Clean".

Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, preintegration-test, integration-test, post-integration-test, verify, install, deploy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy.

maven 生命周期文档没有明确指出它，但 pom 设置确实暗示了 Properties

注意：虽然环境变量本身不区分大小写 Windows，属性查找区分大小写。换句话说，虽然 Windows shell 为 %PATH% 和 %Path% 返回相同的值，Maven 区分 ${env.PATH} 和 ${env.Path}。的名字为了方便起见，环境变量被标准化为全部大写可靠性。

另外，请阅读我对您的问题的评论。如果您觉得此答案有用，请标记为“已回答”（勾选框）。
