Question

我从Eclipse Kepler切换到Eclipse 2018-09。到目前为止，一切都很好，但在事情上：导航器现在始终为空。

我有弹出菜单，并且能够创建一个项目。项目已创建，我可以在代码中无问题地使用它。但是导航器只显示一个空菜单项。如果我右键单击它，则可以看到该项目的弹出菜单。我可以关闭该项目，例如所有其他项目。但是菜单项未显示任何文本。

如果刷新导航器，则菜单项将消失，并且在我重新启动应用程序时也不会再显示。

有什么主意吗？谢谢

编辑：

我创建了一个新项目，并使用了邮件演示应用程序。然后，我添加了导航器插件和导航器资源。同样的问题。然后我添加了Java支持，现在“保存并启动”对话框中存在相同的问题。

Screenshot with Error

edit2：

我也没有丢失插件的错误。但是作为测试，我将每个插件都添加到了应用程序中，但导航器仍然为空。然后我记得我必须在Kepler中添加一个Hack。作为测试，我删除了该hack，开普勒的Navigation也为空。

现在的问题是preStartup（）中的 WorkbenchAdapterBuilder.registerAdapters（）; 不再可用，如果我将其取出，导航栏将再次为空。

Answer 1

在ApplicationWorkbenchAdvisor中添加

@Override
public void initialize(IWorkbenchConfigurer configurer) {
    configurer.setSaveAndRestore(true);
    IDE.registerAdapters();
}

我的RCP应用程序中的导航器始终为空
