Eclipse 缺少必需的类：org/codehaus/gmaven/mojo/GroovyMojo试图在Maven项目中运行以生成报告并发送电子邮件时

我有一个Maven JUnit项目，它成功地编译、构建和测试。同样，当我运行

mvn站点时，所有测试都会成功运行，并在
。\target\site..
目录下生成surefire报告

现在，我需要将此报告发送电子邮件给给定的收件人

这是我的POM：

我能够解决这个问题。我做了以下几件事：

删除了
。/org/apache/maven
文件夹的内容
删除了
。/ch/
文件夹的内容（我认为这是转折点）
重建Maven项目
运行
mvn站点
命令
已成功发送带有
surefire report.html
附件的电子邮件
为什么
maven postman plugin
被声明为依赖项？你们并没有在你们的代码中使用它的类型，是吗？我试着只在插件部分添加它，但并没有成功。所以我也在依赖项中添加了它。我被困在里面了。错误状态之一，一个必需的类缺少“org/codehaus/gmaven/mojo/GroovyMojo”工件是否在您的本地存储库中？我的本地存储库中有gmaven mojo 1.5，这是我在POM的依赖项中添加的内容。根据其POM，我在
maven postman插件：0.1.6
上链接了
requires
gmaven mojo:1.2
。
