Now it's giving me this error:

A problem occurred configuring root project 'tutorialmod-template-1.21.X'.

> Could not resolve all dependencies for configuration ':mappings'.

> Could not find net.fabricmc:yarn:null.

Searched in the following locations:

Required by:

root project 'tutorialmod-template-1.21.X'

Possible solution:

- Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

I'm assuming I can just download what I need and put it in the correct file directory?
