Multi-project setup with Gradle for Android

Question

I am having a problem to make my Android application build.

I have one Main application module, and another one that is needed for the google-play-services_lib.

My folder structure is as follows:

ParkingApp
   | 
   |-----> google-play-services_lib (Library Project) 
   |-----> ParkingApp
   |-----> settings.gradle

My settings.gradle file is as follows:

include ':ParkingApp', ':google-play-services_lib'

My ParkingApp has the following build.gradle.

buildscript {
    repositories {
        maven { url 'http://repo1.maven.org/maven2' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4'
    }
}
apply plugin: 'android'

dependencies {
    compile files('libs/android-support-v4.jar')
    compile project(':google-play-services_lib')
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 17
    }
}

And the google-play-services_lib has the following build.gradle:

buildscript {
    repositories {
        maven { url 'http://repo1.maven.org/maven2' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4'
    }
}
apply plugin: 'android-library'

dependencies {
    compile files('libs/google-play-services.jar')
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 17
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            res.srcDirs = ['res']
        }
    }
}

Any help is appreciated!

@Frohnzie I saw your answer, but I get the same problem. E/dalvikvm: Could not find class 'com.google.android.gms.maps.MapFragment', referenced from method com.example.MainActivity.onCreate — Spase Markovski, May 27 '13 at 16:42

With the new updates in Android Studio and Gradle, I think a better solution for adding support package and google play services jars is to use the maven repositories instead of adding the library it self, here is how you can add both to any .gradle file, using this way you will no have more problems adding both to dependent projects.

dependencies {
    compile 'com.google.android.gms:play-services:3.1.36'
    compile 'com.android.support:support-v4:13.0.+'
}

Note: In the new version of Android Studio 0.2.0, you will need also to update the gradle verison to:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

Put google-play-services.jar in MyParkingApp/libs and reference it as a dependency from MyParkingApp/build.gradle.
