Hi Everyone!
I got some trouble with adding mods to my development environment.
I've set up my development environment as instructed by the forge documentation and added a mod (refined storage) to my run/mods folder.
When I then start minecraft by running it in eclipse it crashes while loading the game.
Here is a example of the crash report:
I've also tried this with other mod's and they also error on the java.lang.RuntimeException: java.lang.ClassNotFoundException with different classes.
I would love some help with this becouse I am out of idea's.
