How to reference dependencies packages into an Android Library like .aar file?

问题

I have an android-library plugin that uses several android libraries included as .jar files and referenced directly from my build.gradle file :

compile fileTree(dir: 'libs', include: '*.jar')

I would then issue a gradlew assembleRelease command to create a .aar file that would be usable within an android application. This has always been working well for me up to now.

I now need to use the Google Play Services in my android-library. As it is instructed in the official Android documentation (http://developer.android.com/google/play-services/setup.html#Setup), I need to include the Google Play Services as a library project by importing it from maven :

compile 'com.google.android.gms:play-services:4.3.23'

But when I build my .aar file, the Google Play Services do not seem to be included in it (my .aar file is only 200kb, and the Google Play Services .jar library is > than 1mb).

I've read that the Google Play Services should be referenced as an Android Library Module, but I can't manage to import it like that without compilation errors. Can someone help me to have the Google Play Services packaged into my android-library?

My android-library build.gradle file :

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}
apply plugin: 'android-library'

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.google.android.gms:play-services:4.3.23'
    compile fileTree(dir: 'libs', include: '*.jar')
}

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.1'

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 19
    }
    release {
        runProguard false
    }
}

My android application build.gradle file :

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
    flatDir {
        dirs 'libs'
    }
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.1"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 19
    }
    buildTypes {
        release {
            runProguard true
            proguardFile getDefaultProguardFile('proguard-android-optimize.txt')
        }
    }
    productFlavors {
        defaultFlavor {
            proguardFile 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile 'novom.anyware.anywaresdk:anywaresdk:0.1.0@aar'
}

When issuing a gradle dependencies from the root of my main module, here is my result :
