Gradle + Robolectric + Espresso: can't run separately - testing

Question

I tried to adapt following template: deckard-gradle
I use Android Studio 0.8.14 (beta).
This is my build.gradle:
apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'robolectric'
android {
compileSdkVersion 21
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "com.example.myapp"
minSdkVersion 18
targetSdkVersion 21
versionCode 1
versionName "1.0"
testInstrumentationRunner "com.google.android.apps.common.testing.testrunner.GoogleInstrumentationTestRunner"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
sourceSets {
androidTest {
setRoot('src/test')
}
}
packagingOptions {
exclude 'META-INF/LICENSE.txt'
exclude 'LICENSE.txt'
exclude 'META-INF/LICENSE'
exclude 'META-INF/NOTICE'
}
}
robolectric {
include '**/*Test.class'
exclude '**/espresso/**/*.class'
}
configurations {
apt
}
apt {
arguments {
resourcePackageName android.defaultConfig.packageName
androidManifestFile variant.outputs[0].processResources.manifestFile
}
}
ext {
daggerVersion = '1.2.2';
androidAnnotationsVersion = '3.2';
robobindingVersion = '0.8.9';
jodatimeVersion = '2.5.1';
ormliteVersion = '4.48';
ottoVersion = '1.3.5';
commonsioVersion = '2.0.1';
playservicesVersion = '6.1.71';
supportv4Version = '21.0.2';
javaxinjectVersion = '1';
junitVersion = '4.11';
robolectricVersion = '2.4';
}
dependencies {
// Espresso
androidTestCompile files('libs/espresso-1.1.jar', 'libs/testrunner-1.1.jar', 'libs/testrunner-runtime-1.1.jar')
androidTestCompile 'com.google.guava:guava:14.0.1'
androidTestCompile 'com.squareup.dagger:dagger:1.2.2'
androidTestCompile 'org.hamcrest:hamcrest-integration:1.1'
androidTestCompile 'org.hamcrest:hamcrest-core:1.1'
androidTestCompile 'org.hamcrest:hamcrest-library:1.1'
androidTestCompile("junit:junit:${junitVersion}") {

}
androidTestCompile("org.robolectric:robolectric:${robolectricVersion}") {

exclude module: 'plexus-interpolation'
exclude module: 'plexus-utils'
exclude module: 'wagon-file'
exclude module: 'wagon-http-lightweight'
exclude module: 'wagon-provider-api'
}
androidTestCompile 'com.squareup:fest-android:1.0.+'
apt "org.robobinding:codegen:$robobindingVersion"
compile("org.robobinding:robobinding:$robobindingVersion:with-dependencies") {
exclude group: 'com.google.guava', module: 'guava'
}
apt "org.androidannotations:androidannotations:${androidAnnotationsVersion}"
compile "org.androidannotations:androidannotations-api:${androidAnnotationsVersion}"
apt "com.squareup.dagger:dagger-compiler:${daggerVersion}"

compile group: 'commons-io', name: 'commons-io', version: "${commonsioVersion}"
compile "net.danlew:android.joda:${jodatimeVersion}"
}
apply plugin: 'idea'
idea {
module {
testOutputDir = file('build/test-classes/debug')
}
}
android.applicationVariants.all { variant ->
def aptOutput = file("${project.buildDir}/generated/source/apt/${variant.dirName}")
println "****************************"
println "variant: ${variant.name}"
println "manifest: ${variant.processResources.manifestFile}"
println "aptOutput: ${aptOutput}"
println "****************************"
variant.javaCompile.doFirst {
println "*** compile doFirst ${variant.name}"
aptOutput.mkdirs()
variant.javaCompile.options.compilerArgs += [
'-processorpath', configurations.apt.getAsPath(),
'-AandroidManifestFile=' + variant.processResources.manifestFile,
'-s', aptOutput
]
}
}
I tried to ways to run unit tests:
When I use gradlew test I get exceptions because all tests (also instrumentation) are executed.
When I use Android Studio to run a JUnit test I get this error:
!!! JUnit version 3.8 or later expected:
java.lang.RuntimeException: Stub!

For various reasons, I've abandoned the above approach in favor of keeping my Robolectric tests in a Gradle submodule. You can find a blog post I wrote about why I moved in this direction and a fork of the deckard-gradle project that shows you how here.
