我有一个现有的RCP应用程序，它运行在第3.7版。我试图通过包括依赖的jar将其迁移到4.3。但是在启动应用程序后，我无法显示任何导航视图。我收到了打击错误
ERROR: Unable to find Action Set: org.eclipse.ui.edit.text.actionSet.annotationNavigation
LogListener: ERROR: >> Exception object is null
LogListener: ERROR: Unable to find Action Set: org.eclipse.ui.edit.text.actionSet.navigation
LogListener: ERROR: >> Exception object is null
我包括上述两个类的类正在扩展ActionBarAdvisor。
我得到的另一个例外是

这些操作集位于org.eclipse.ui.editors插件中。确保您已将其包含在RCP版本中。
