Gradle plugin for running local robolectric test

Gradle plugin to run robolectric tests. It is hackishly working. The main issue with the Android plugin is the way that it declares build variances and sourcesets - which are not Gradle sourcesets. Currently the plugin does a brute force when it comes to addings jars (from aar, folders, configs).

We aim to achieve the following:

buildscript {
    repositories {
        mavenCentral()
        maven {
        	url "https://oss.sonatype.org/content/repositories/snapshots"
    	}
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4.2'
        classpath 'com.novoda.gradle:robolectric-plugin:0.0.1-SNAPSHOT'
    }
}

apply plugin: 'android'
apply plugin: 'robolectric'

repositories {
    mavenCentral()
    mavenLocal()
    maven {
        url "https://oss.sonatype.org/content/repositories/snapshots"
    }
}

dependencies {
    //compile files('libs/android-support-v4.jar')

    // had to deploy to sonatype to get AAR to work
    compile 'com.novoda:actionbarsherlock:4.3.2-SNAPSHOT'

    robolectricCompile 'org.robolectric:robolectric:2.0'
    robolectricCompile group: 'junit', name: 'junit', version: '4.+'
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 17
    }
}

Originally, with no plugin, you could write along the lines of the following build.gradle

import com.android.build.gradle.internal.tasks.BaseTask
import org.gradle.api.internal.file.collections.SimpleFileCollection
import org.gradle.api.tasks.testing.Test

import java.util.concurrent.Callable

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.4.2'
    }
}

repositories {
    mavenCentral()
    mavenLocal()
    maven {
        url "https://oss.sonatype.org/content/repositories/snapshots"
    }
    maven {
        url "https://github.com/novoda/public-mvn-repo/raw/master/releases"
    }
}

apply plugin: 'android'
