Eclipse - Minecraft source visible, BUT not forge or fml source

[Pardeep]

My eclipse is setup correctly and I can mod and run and it's all fine. But my problem is this:

 

In the reference libraries, you can look at all the minecraft vanilla files e.g. net.minecraft.entity.player.EntityPlayer.class

 

BUT, if I want to open any file from FML or MinecraftForge, it just says the source is not attached, even though the location of the source is correct (as I can see all the vanilla minecraft stuff). An example is net.minecraftforge.event.entity.player.PlayerUseItemEvent.class

 

I've tried running setupDecompWorkspace, setupDevWorkspace, deleting and reinstalling everything. Still none of the forge or fml source is visible in eclipse.

Any help (if it helps, I use JDK8u5, but I have eclipse already patched for that so that shouldn't be the issue).

 

Thanks in advance.

MinecraftForge does not work with Java 8. Uninstall and use Java 7.

Was an issue on my fault.

You may continue to use Java 8, java 8 works fine.

 

gradle clean cleanEclipse cleanCache --refresh-dependencies
gradle setupDecompWorkspace eclipse --refresh-dependencies

 

and everything should be fixed. Was a character encoding issue.
