Forge 1.12.2 crashing on startup, help!

[Jojo_Reference]

When I try to run this simple mod that adds one item with a item texture, the game crashes shortly after Minecraft begins loading.

It didn't do this before I tried to add the texture.

My code: https://github.com/FabulousAmpharos/ModTutorial/tree/master/myfirstmod

I followed McJty's tutorial.

The crashlog:

Thank you, that fixed the issue. Also thanks for warning me about the domain name, I didn't know that was important.
