Industrialcraft 2 API Error

I'm having a weird bug when trying to run forge src with IC2 in the mods folder. Please look over the error
and see if you can find a way to fix it for me

P.S. I'm a newbie at mod developing, so I might have screwed up somewhere along the way

Are you using 1.115, or 1.111?

I am using 1.112, I guess I should update to 1.115?

EDIT: Update didn't change a single thing
