Eclipse插件项目运行配置

Question

有谁知道如何解决这个问题？

我正在与GEF一起做一个插件项目。 当我选择Run As> Run Configurations ...> Eclipse Application> New launch configuration时，我创建了一个新的Eclipse Application。 然后在Main选项卡中我放置了这个位置：$ {workspace_loc} /.metadata / .plugins / org.eclipse.pde.core / runtime-New_configuration。 在我的xml文件中，我描述了我的应用程序：

   <extension
         id="application"
         point="org.eclipse.core.runtime.applications">
      <application>
         <run
               class="tutogef.Application">
         </run>
      </application>

当我执行插件时，它显示以下消息：

最简单的方法就是重新安装你的eclipse程序，它会像往常一样再次运行。 这是一个最好的方式，如果要搜索答案，你将浪费你的时间和平。 ;）
