Hello,
I will add some mods in eclipse because I want to program a pipeline which carries fluids and for that I need existing tanks and api's.
So I added Buildcraft, Industrialcraft and Railcraft to my Mods/ folder and run eclipse. Then it starts, loads all mods and crashes:
java.lang.NoSuchMethodError: net.minecraft.command.ICommand.func_71517_b()Ljava/lang/String;
It happens to each mods, even when I add only one mod.
Can anyone help me to add mods and an api?
I know that today started another thread about api's (http://www.minecraftforge.net/forum/index.php/topic,31525.0.html), but it wasn't helpful because I haven't got a "src/api" folder in my forge folder.
