Adding a support library in Robolectric 2.3

After inspiration from this template, I was able to get roblolectric and espresso tests working with Android and gradle. The key was to store the robolectric in its own module. However, I cannot add a support library to robolectric. How can i do this?

Here's the gradle file of the robolectric module:

apply plugin: 'java'

// * What went wrong:
// Execution failed for task ':robolectric-tests:test'.
//        > superClassName is empty!
tasks.withType(Test) {
    scanForTestClasses = false
    include "**/*Test.class"
}

dependencies {
    def androidModule = project(':App')
    compile androidModule
    testCompile androidModule.android.applicationVariants.toList().first().javaCompile.classpath
    testCompile androidModule.android.applicationVariants.toList().first().javaCompile.outputs.files
    testCompile files(androidModule.plugins.findPlugin("com.android.application").getBootClasspath())
    testCompile 'junit:junit:4.+'
    testCompile ('org.robolectric:robolectric:2.3') {
        exclude module: 'support-v13'
        exclude module: 'support-v4'
    }

}

Here is the top level gradle project. As you can see, I bring the correct repo, because the App module does not create any problems.

ext {
    versions = [
        findbugs: '2.0.3',
        checkstyle: '5.7',
        pmd: '5.1.1'
    ]
}

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.1+'
        classpath group: 'com.autoscout24.gradle', name: 'gradle-monkey-plugin', version: '0.7+'
        classpath 'de.felixschulze.gradle:gradle-hockeyapp-plugin:2.1+'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

Robolectric requires the Google APIs for Android (specifically, the maps JAR) and Android support-v4 library. To download this onto your development machine use the Android SDK tools and then run the following to install them to your local Maven repository:

mvn install:install-file -DgroupId=com.google.android.maps \
  -DartifactId=maps \
  -Dversion=18_r3 \
  -Dpackaging=jar \
  -Dfile="$ANDROID_HOME/add-ons/addon-google_apis-google-18/libs/maps.jar"

mvn install:install-file -DgroupId=com.android.support \
  -DartifactId=support-v4 \
  -Dversion=19.0.1 \
  -Dpackaging=jar \
  -Dfile="$ANDROID_HOME/extras/android/support/v4/android-support-v4.jar"
