IntelliJ 13 select Groovy SDK from Gradle dependencies - intellij-idea

Question

For my Android project I want to run a test HTTP server for my integration tests. I've created a Configuration and have written a task to run my Groovy script the sets up the HTTP server
configurations {
stubs {
description = "Classpath for HTTP server for stubbed data"
visible = false
}
}
dependencies {
compile "com.android.support:support-v13:+"
stubs "org.codehaus.groovy:groovy:2.3.4"
stubs "com.github.tomakehurst:wiremock:1.46"
}
When I edit the Groovy script IntelliJ tells me that the Groovy SDK hasn't been configured.
How can I have IntelliJ use the Groovy SDK that is part of the stubs Configuration? I can't create a Groovy SDK configuration using the Gradle fetched libraries as IntelliJ tells me that the Groovy distribution is broken because the version number can't be determined.
Am I forced to have to download the distribution manually?

The solution was to separate out the project for the HTTP server into a separate project and use Gradle's multiproject's ability to set up the Android tests to depend on the HTTP server being started. Because the separate project is a Groovy project, IntelliJ reads the Groovy version to use from the project's dependencies and all is well.
dependencies {
compile "com.android.support:support-v13:+"
stubs project(":integration-server")
}
/*

*/
gradle.projectsEvaluated {
connectedAndroidTest.dependsOn(":integration-server:startBackgroundServer")
// Note: finalizedBy is still #Incubating
connectedAndroidTest.finalizedBy(":integration-server:stopBackgroundServer")
}
integration-server/build.gradle
apply plugin: "groovy"
apply plugin: "spawn"
dependencies {
compile "org.codehaus.groovy:groovy:2.3.4"
compile "org.codehaus.groovy:groovy-ant:2.3.4"
compile "com.github.tomakehurst:wiremock:1.46"
}
task startBackgroundServer(type: SpawnProcessTask, dependsOn: "build") {
def cp = sourceSets.main.runtimeClasspath.asPath
command "java -cp $cp server"
ready "Started DelayableSocketConnector#0.0.0.0:8089"
}
task stopBackgroundServer(type: KillProcessTask)
To prevent the Gradle build blocking I'm using a Gradle Spawn Plugin to launch the HTTP server in the background.
