How might one properly register a server command without throwing an AbstractMethodError? I've currently got one command registered, which works just fine within eclipse, however, when I export the mod, the mod loads just fine but when the command is entered it throws an AbstractMethodError and barfs up a bunch of locations it's throwing the exception.

 

Here's how I'm registering the command:

 

@EventHandler

@SideOnly(Side.SERVER)

public void serverLoad(FMLServerStartingEvent event) {

    event.registerServerCommand(new ZeusCommand());

}

 

Here's the error it's throwing:

I've looked at one other mod, Morpheus (by Quetzi), which uses the same method of registering the command, and I'm using it the same way. Any tips?

Are you properly reobfuscating your mod? From this:

 

java.lang.AbstractMethodError

at net.minecraft.command.CommandHandler.func_71560_a(CommandHandler.java:119)

 

I'm guessing that either your mod wasn't reobfuscated, or you're not implementing all of the required ICommand methods. Since your code compiles in eclipse, it's more likely that your mod wasn't property reobfuscated. I've used this code myself to successfully register server commands. In my mod, my commands extend CommandBase, because it implements a few useful methods for you.
