Sorry, but I'd just like to say for anyone else stumbling in here, I solved my problem in IntelliJ IDEA by doing a Ctrl+Shift+F search for every occurrence of 'examplemod' and replacing them all with my own modID.
I still having this problem now, a month later. Is it a bug in the beta version of Forge, or did I forget to remove 'examplemod' from one of the config files? I thought I'd found all the occurrences of it...
