maven jetty debug LifecyclePhaseNotFoundException异常

发到这个板块也不知道合适不合适，实在没办法了

maven项目想使用jetty调试，这个异常怎么也过不去，按照最后官方的那个wiki各种clean也还是不行。

有明白人，还请指教。。。。

setting.xml中也加入了
  <pluginGroups>
        <pluginGroup>org.mortbay.jetty</pluginGroup>
   </pluginGroups>

对了，补充一下。在命令行中jetty:run是可以启动的，只有在eclipse中启动才会报这个错误

MAVEN_OPTS=-Xms128m
X前的-号是干嘛的？
