I'm using:
MDK 1.17.1
JDK 8

I'm config the mods.toml file:

  [[dependencies.randommod]]
    modId="minecraft"
    mandatory=true
    versionRange="[1.17.1]"
    ordering="NONE"
    side="BOTH"

When I execute runClient, the game load and wait for something with the message: File mod file C:\eclipse-workspace\project\build\resources\main failed to load a valid ResourcePackInfo

Any idea?

I have not found nothing about "pack.mcmeta" on forge documentation. I only find that file when download a new MDK but I think it's configurated for 1.16.2 version, not for 1.17.1

Can you give me some link? thanks
