If you came here looking for the Gradle Android Maven plugin, I have renamed the project following a request from the android-maven-plugin developers.
For the android-maven-gradle-plugin go to: https://github.com/dcendents/android-maven-gradle-plugin (To let you install your aar libraries into the local maven repository)
For the android-maven-plugin go to: https://github.com/simpligility/android-maven-plugin (To do android development using maven)
