Class 'net.minecraftforge.userdev.LaunchTesting' not found in module (forge 1.15.2-31.2.0)

[MainPucci]

Hi! I cannot run my Minecraft Mod with forge (1.15.2-31.2.0).

 

I'm using Intellij to write and execute the code.

 

On the runClient configuration appears that: Warning: Class 'net.minecraftforge.userdev.LaunchTesting' not found in module 'Test' (Test is the name of my module)

 

I have already runned this command on the CMD:

gradlew genIntellijRuns   

 

 

This is the error message:

I suppose you mean "Could not find net.minecraftforge:forge:1.15.2-31.2.0_mapped_snapshot_20200514-1.15.1."

I tried reinstalling forge for the client and redownloading the mdk (both on the same version) and none of that worked
