Make throws errors for the Andengine multiplayer extension, but they don't show up in the Intellij IDEA editor window

Question

I am trying to run the Andengine examples in the IntelliJ IDEA. I managed to import all the necessary extensions and the editor window doesn't show any errors anymore, but when I try to run the project and it compiles all of the classes it shows several errors:

/home/mathias/Arbeitsplatz/andenginemultiplayerextension/src/org/anddev/andengine/extension/multiplayer/protocol/server/SocketServerDiscoveryServer.java
  cannot find symbol class IDiscoveryData
/home/mathias/Arbeitsplatz/andenginemultiplayerextension/src/org/anddev/andengine/extension/multiplayer/protocol/server/SocketServer.java
  cannot find symbol class IServerListener
  ... and so on

It seems the library can't find some of its own classes, although they are all there, and there are no errors shown in the editor.

I found this issue on the project page which shows the same errors in eclipse, although I found no description on how to fix it.

I have no custom build settings for this project and all I do is click on the "Run"-Button.

Answer 1

there is solution from here: http://youtrack.jetbrains.com/issue/IDEA-79464 :

Same error here with intellij 11.0.2, though a quick patch I found is to set intellij to use Eclipse compiler in the settings/compiler menu (there are several options) and everything seems to compile properly.

Answer 2

我在其他地方找到的只是一个解决方案-将IntelliJ设置为使用Eclipse编译器。
