I've been working for a while trying to just make my first mod. I've downloaded IntelliJ, downloaded the MDK, and opened the build.gradle file as a project. I've watched many tutorials, following exactly as they say, but when I open the project the Gradle menu is simply empty. It Says there is nothing to show. I have downloaded the same MDK's and followed the same instructions, so I am lost as to what I could be doing wrong. I know that I should be able to run setupDecompWorkplace but that entire menu is non-existent. Edit: Tried making the suggested change (Importing Gradle Changes) and still the same situation. No tasks appear in the Gradle side bar and now it is throwing additional errors as well (see 2nd photo.)
