I'm very new at making a minecraft mod, and I'm stuck at trying to make a basic item. Whenever I try to run the mod, it crashes with this wall of errors:

I'm using Netbeans to edit the files, and have the most recent versions of Minecraft Forge, Java, and Minecraft. I've looked around a lot but can't find a solution that works for me. Can anyone help? The full files are here if you want to take a look at them: https://drive.google.com/file/d/0B2ST0CgMxTEZd0pzTWl4MF9ybk0/view?usp=sharing

I've compiled it it into a .JAR file, put it into the mods folder, and attempted to launch the game.

Ah! That did it.

 

My item is now a purple and black box, but at least it exists. I'll see if I can't figure it out some more from here. Thanks a lot.
