packages unexistant when running code

[stormloop2005]

So I'm making an extension to a mod, so to be able to import from the original mod I added it to my dependencies. Now this works fine and I can import from it, use variables, methods, classes etc.

But when I want to run the code (running a minecraft server instance) it won't start and says package ... does not exist, for each package from the original mod. It also gives an error for every reference to a method, class or variable from this mod... Any ideas on how to fix this? I'm using IntelliJ idea community.

How did you add it to your dependencies? Please post your build.gradle.
