I am trying to use a Mod I developed as an API, but I have no idea how. I do not intend to have it download from the internet or anything like other really popular APIs, just use a Jar file. The only tutorials I have been able to find have been really old, from 2014 or earlier. Does anyone know how to do this?

If you're using gradle, it's as simple as declaring a directory to be a repository.

repositories {
    flatDir {
        dirs 'libs'
    }
}

dependencies { implementation name: 'my-jar-file-1.0.0' }

I've seen some newer threads online do it like this though:

dependencies { implementation files('libs/my-jar-file-1.0.0.jar') }

There are a lot of Gradle threads online that walk through how to do this. I recommend finding some more for yourself if these don't work.

I tried implementation name, but gradle is telling be I should be using implementation fg.deobf(), but how would I do that?

Edit: I fixed it.
