在写Eclipse RPC应用的时候遇到了Authorization infrastructure (org.eclipse.core.runtime.comp

在写Eclipse RPC应用的时候遇到了Authorization infrastructure (org.eclipse.core.runtime.compatibility.auth) not installed的异常，具体如下：

!MESSAGE Authorization infrastructure (org.eclipse.core.runtime.compatibility.auth) not installed.

在*.product中的Configuration->Add Required Plug-ins添加RCP plugin project所需的所有支持包即可（自己是这样做的）。
另外网上有其他的解决方法：
解决办法是在Dependencies列表里加入org.eclipse.core.runtime.compatibility.auth，并且放在org.eclipse.core.runtime之前。
我试过了，对于导出的项目来说，这中做法好像不行。
