1.16.5 - Error after trying to shadow a dependency

JustinB0406 · August 19, 2021

I am trying to shadow GeckoLib3 into my mod. However, every time I build the jar file and launch Minecraft with it, I get "mods.toml missing metadata for modid geckolib3." How can I fix this?

So I got the jar working by copying and pasting GeckoLib's mods.toml into my own. However, I still can't run the mod on my dev environment. It gives this error:
