Cannot find symbol variable DaggerTestComponent

Question

Im trying to inject my App Component like this because Im using this boilerplate.

private void setupDaggerTestComponentInApplication() {
    WSApplication application = WSApplication.get(mContext);
    mTestComponent = DaggerTestComponent.builder()
            .applicationTestModule(new ApplicationTestModule(application))
            .build();
    application.setComponent(mTestComponent);
}

This is located in a new testing folder:

sourceSets {
    def commonTestDir = 'src/commonTest/java'
    test {
        java.srcDir commonTestDir
    }
    androidTest {
        java.srcDir commonTestDir
    }
}

DAGGER_VERSION = '2.11-rc2'

Output:

error: cannot find symbol variable DaggerTestComponent

Any idea? Thanks
