When starting an eclipse instance (using the current development version) that uses the ResourceNavigator plugin, you might experience an exception during startup.

This causes the navigator view to display nothing but a grey box. It took me some time to figure out what went wrong here, especially since the validation of the plug-in set did not show any problems. You have to enable


org.eclipse.core.runtime.compatibility 

in order to get the resource navigator working.
------------------------
即当ResourceNavigator在RCP程序中无法正常调用时,需要在依赖项中增加一个兼容性插件
org.eclipse.core.runtime.compatibility。这个办法很好地解决了我遇到的问题。

多谢,问题解决了,我原来还以为升级eclipse版本就方法不支持了呢,再次感谢!
