重命名 eclipse e4 应用程序模型文件

Question

当我使用 Refactor->rename 功能将文件 Application.e4xmi 重命名为 something.e4xmi 时，我无法再启动我的 e4 应用程序。我还确保在 plugin.xml 文件中产品属性设置为相同的名称：

     <property
       name="applicationXMI"
       value="something.e4xmi">
     </property>

我得到了同样的结果。 最后，我完全删除了该部分，再次没有运气。

错误是：

applicationXMI 属性值应包含插件 id：

<property
   name="applicationXMI"
   value="plugin-id/something.e4xmi">
</property>
