Life saver! You should send this to @robolectric guys!

I did some small changes here in order to work:

• Test if iml file exists. If you clone a repo from scratch or use a CI server you'll have an error

    def parsedXml;
    try {
        parsedXml = (new XmlParser()).parse(imlFile)
    }
    catch (Exception e) {
        println 'iml file not found, nothing to do here!'
        return
    }

• Following this guide -- https://github.com/marcoRS/gradlectric -- I changed the output test folder:

    component.appendNode('output-test', ['url': "file://\$MODULE_DIR\$/build/test-classes"])

And it's working for me on both Android Studio (1.0 RC4) and IntelliJ (14.0.2 RC EAP) .. Hope you find useful!

In my case it works (AS 1.0 RC4) to move jdk to the end of my iml file but I keep the error
Class not found
even if i run testDebugClasses before test

thanks, It was temporary fix.
I'm looking for a good solution, try https://github.com/bademux/robolectric-java-gradle-plugin .
And here the usage example https://github.com/bademux/deckard-gradle

Seems that robolectric guys aren't happy with my solution: https://groups.google.com/d/msg/robolectric/nJgHtdbkpi8/VUTn1mEcMqEJ

bugreports and patches are welcomed

@fcduarte I applied you patch, thanks. AS will magically replace $project.buildDir with $MODULE_DIR so no problem here.
But as I said, it is ugly hack for unsupported solution (placing Robolectric in the same project with Instrumention tests). It is better to find a way to move robolectric tests to another project and play with classpath.

I wrote a Gradle plugin to integrate Robolectric tests into Android Studio with minimal configuration.
