I get this error whenever I try to test my mod in eclipse. There are absolutely no errors in my code, and when I launch Minecraft through magiclauncher it works fine. Mod source code: http://github.com/DigitallyNative/Minextension1

I get the following error every-time I try to run my mod in eclipse.

None have worked. Minecraft will run fine through the launcher and it's using the same version. I am new to java and don't have much experience with it. I would guess the error is to do with LMZA files, but I don't know how to fix. Thank you for reading answer as soon as possible because I'm going on holiday tomorrow.
