How do I get IntelliJ to recognize gradle generated sources dir?

Question

So I have an XJC javaExec that spins like a top but IntelliJ doesn\'t recognize the generated output despite having marked generated-src/java as such. Do I need to

I'll point out a solution by Daniel Dekany, from a Gradle discussion thread actually linking to this question. To quote:

apply plugin: "idea"
...
sourceSets.main.java.srcDir new File(buildDir, 'generated/javacc')
idea {
    module {
        // Marks the already(!) added srcDir as "generated"
        generatedSourceDirs += file('build/generated/javacc')
    }
}

Works well for me.
