Alternatively, you could use the android-maven-plugin:

// root build.gradle
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.2'
        classpath 'com.github.dcendents:android-maven-plugin:1.0'
    }
}

// library build.gradle
apply plugin: 'android-maven'
version = "1.0.0"
group = "com.example"
archivesBaseName = "awesome-library"
