what am I doing wrong?

I've configured the dependencies incorrectly, should be fixed in a bit.

Also gonna change to cloth config rather than cotton config, so that might also fix it.

Might be caused by modmenu recently moving their maven url, if you were building the fabric version.

Edit: the url wasn't loading on my end, it caused gradle not to build the mod.

Gradle has been configured completely incorrectly in both Fabric and Forge, finally fixed everything and will be releasing a fixed version soon.
