EclipseRCP:Application"；org.eclipse.ui.ide.workbench“；在注册表中找不到

我是Eclipse RCP的新手。我正试图在EclipseJuno上建立一个RCP项目。
将所有插件导入我的工作区后，我在尝试运行应用程序时遇到以下错误：

java.lang.RuntimeException: Application "org.eclipse.ui.ide.workbench" could not be found in the registry.

我可以知道如何解决此错误吗？

插件

org.eclipse.ui.ide

需要在您的启动配置中

在菜单中转到：运行>运行配置

如果您不想启动EclipseIDE而是自己的应用程序，则需要更改启动“运行应用程序”的“主”选项卡。
要创建自己的应用程序，请搜索

org.eclipse.core.runtime.applications
