I would like to know how to properly compile the World of Minecraft.jar file, as I am trying to add in the client mini-map add-in. I am aware there are builds of it by other members, but I am curious as what to do to get it to compile, Its just sort of a curiosity on how to build it, because I haven't been able to.

I get it de-compiled (DJ Java De-compiler) into .java files, then upon doing..

javac Main.java

It errors.

Thanks for any help..

(I'm a java noob..)
