The problem is that Groovy Android Gradle plugin (to have Groovy working on Android) isn't simply working with Android plugin in version 1.1.0-rcX.

Here's a very interesting piece of code directly from groovyx.grooid.GroovyAndroidPlugin, version 0.3.5 (current latest, here's the source)

    def getRuntimeJars(Project project, plugin) {
    int index
    switch (getAndroidPluginVersion(project)) {
        case ~/0\.9\..*/:
            index = 0
            break
        case ~/0\.10\..*/:
        case ~/0\.11\..*/:
        case ~/0\.12\..*/:
        case ~/0\.13\..*/:
        case ~/0\.14\..*/:
        case ~/1\.0\..*/:
            index = 1
            break
        default:
            index = RUNTIMEJARS_COMPAT.size()-1
    }
    def fun = RUNTIMEJARS_COMPAT[index]
    fun(plugin)
}

and definition of RUNTIMEJARS_COMPAT:

private static List RUNTIMEJARS_COMPAT = [
        { it.runtimeJars },
        { it.bootClasspath }
]

So that API must have changed in Android Gradle between 0.9.x and 0.10.0 (yeah, I know - those Google devs change everything there :[ ). So let's take a look at that problem making class in Android Plugin version 1.0.0:

> javap -cp [path to proper jar] com.android.build.gradle.AppPlugin:

public class com.android.build.gradle.AppPlugin extends com.android.build.gradle.BasePlugin implements org.gradle.api.Plugin {
...
public java.util.List super$2$getBootClasspath();
...

Yup! There's the method we need (coming from parent com.android.build.gradle.BasePlugin class). Now there's nothing like that in version 1.1.0-rc3. What's more, the API of com.android.build.gradle.AppPlugin is completely changed, so it's not a matter of simple if(version) to fix that.

I guess there's no chance to have Groovy Android Gradle plugin working with Unit Tests (since 1.1.0) until authors update the plugin.

Let's wait then.
