Hello,
I'm not completly new to modding and I'm using IntelliJ as my IDE.
I wanted to rewrite a mod of mine and created a new project for it. After i used the setupDecompWorkspace I started coding and at the first run it told me for every single forge package that it doesn't exist.
Even though it wouldn't tell me that whilst editing. However this only happens if I use the Application config. If I use runClient it works fine... And I can't find any errors in my build config (for the Application config).
I've tried pasting my old build.gradle, which didn't work, use the setupDevWorkspace, but nothing worked.
I've included a screenshot of my config.
