gmaven没有为groovy代码生成jar文件

Question

我使用GMaven插件在maven中编写groovy代码。当我执行mvn全新安装时，它显示构建成功，但当我检查我的目标文件夹时，它没有为我生成任何jar。我在其中引用了这个atlassian link

<plugins>
  <plugin>
 <executions>
      <execution>
        <goals>
          <goal>generateStubs</goal>
          <goal>compile</goal>
          <goal>generateTestStubs</goal>
          <goal>testCompile</goal>
        </goals>
      </execution>
    </executions>
  </plugin>
</plugins>

但是对于这个问题，我在execution上得到了pom错误。请帮帮我

下面是我的pom文件

更新1：

我可以看到jar，但它没有我的groovy代码。
