What I have done:
I have made i minecraft mod that uses slick2d. I have compiled it into a .jar file. I put the .jar file in the foleder with the appropriate json file. I put that folder into the versions foleder inside .minecraft on my pc.
My problem:
When I try to run the instalation with the minecraft launcher it runs for a few seconds and the mojang loading screen appeares and after a second it crashes. The launcher gives me this error:
The game crashed whilst initializing game Error: java.lang.NoClassDefFoundError: org/newdawn/slick/SlickException Exit Code: -1
I am not sure if I linked the slick.jar file correctly because I cant find any tutorials or anything on the internet. Any help will be appriciated, thanks.
