Hey, I tried to do 

gradlew genIntellijRuns

because I'm in Intelij, but I get this error when running it:

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'mcmod'.
> Could not resolve all files for configuration ':_compileJava_1'.
   > Could not find client-extra.jar (net.minecraft:client:1.16.3).
     Searched in the following locations:
         file:/C:/Users/joshu/.gradle/caches/forge_gradle/bundeled_repo/net/minecraft/client/1.16.3/client-1.16.3-extra.jar

 

Ok I deleted the .gradle folder and did it again, now it worked
