We should publish the ComputerCraft API to a Maven repository to make it easier for other mods to use it.

For reference, to make an api jar, you can use something like this (just need to change the include line)

task apiJar(type: Jar) {
    classifier "api"
    dependsOn "sourceMainJava"
    include 'path/to/api/**'
    from sourceSets.main.java.srcDirs
    from sourceSets.main.output
}

artifacts {
    archives apiJar
}

It's worth noting that https://cc.crzd.me has a sort-of-Maven repository running, which one is free to depend on. That's what OpenComputers and Plethora do:

repositories {
  maven { url "https://cc.crzd.me/maven/" }
}
dependencies {
  compile "dan200.computercraft:ComputerCraft:1.81-build3"
}

Obviously having an official repository would be better, but this is a start.

Even just having the api artifact in the build.gradle would help; I have no issues hosting a copy of it for projects I'm a part of
