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

Answer 1

In my case, it didn't work unless I added the generate sources directory to both sourceDirs and generatedSourceDirs:

def generatedSourcesDir = file('src/generated/main/java')
idea {
  module {
    sourceDirs += generatedSourcesDir
    generatedSourceDirs += generatedSourcesDir
  }
}
