How to import a maven module to an Android Studio project

Question

I would like to include retrofit as a module in my Android Studio project. The problem is that retrofit is a maven project and so Android Studio won't let me import it. Is there a way around this?

A similar question has been asked before, but it received no answers.

Use a custom group and/or artifact in the POM of your clone, so your clone cannot be confused with the original.

Build and install your clone of Retrofit using Maven as usual: mvn install. (Using the command line or an IDE other than Android Studio.) You have to build your Retrofit clone manually after each change you make to it, for Gradle to see the changes.

Add the local Maven repository to your Gradle script. See https://docs.gradle.org/2.5/dsl/org.gradle.api.artifacts.dsl.RepositoryHandler.html#org.gradle.api.artifacts.dsl.RepositoryHandler:mavenLocal():

repositories {
    mavenLocal()
}

Add the GAV of your clone as a dependency to your Gradle script:

dependencies {
    compile 'com.yourgroup:retrofit:1.9.0-custom'
}
