Setting up integration tests in Android Gradle-based project

Question

I'm following this tutorial to add integration test env to my Android project. I have create src/integrationTest/java and src/integrationTest/resources dirs and then I have added this to my build.gradle:

sourceSets {
    integrationTest {
        java {
            compileClasspath += main.output + test.output
            runtimeClasspath += main.output + test.output
            srcDir file('src/integrationTest/java')
        }
        resources.srcDir file('src/integrationTest/resources')
    }
}

But when I sync Gradle files I get this error:

Error:(134, 0) No such property: main for class: org.gradle.api.internal.file.DefaultSourceDirectorySet Possible solutions: name

What does it means? How can I solve it?

Thanks

EDIT

I have just tried with android.sourceSets.main.output and android.sourceSets.test.output instead of main.output and test.output, respectively:

sourceSets {
    integrationTest {
        java {
            compileClasspath += android.sourceSets.main.output + android.sourceSets.test.output
            runtimeClasspath += android.sourceSets.main.output + android.sourceSets.test.output
            srcDir file('src/integrationTest/java')
        }
        resources.srcDir file('src/integrationTest/resources')
    }
}

And now I get this error:

Error:(136, 0) Could not find property 'output' on source set main.

Solved! Actually, these lines don't have to be in source set config, but in the task that runs integration tests. Now, my build.gradle looks like:

    sourceSets {
        integrationTest {
            java.srcDir file('src/integrationTest/java')
            resources.srcDir file('src/integrationTest/resources')
        }
    }

    configurations {
        integrationTestCompile.extendsFrom testCompile
    }

    task integrationTest(type: Test) {
        testClassesDir = sourceSets.integrationTest.output.classesDir
        classpath = sourceSets.integrationTest.runtimeClasspath
    }
