How to specify in Gradle an `@OutputDirectory` for an `Exec` task?

I have the following:

task cloneProtobuf(type: Exec) {
  workingDir "${rootProject.buildDir}/github.com/google"
  commandLine 'git', 'clone', 'https://github.com/google/protobuf.git'

  enabled = { -> !new File(workingDir, "protobuf/.git").isDirectory() }()
  doFirst {
    mkdir workingDir
  }
}

Rather than explicitly setting enabled and having gradle indicate that the task was SKIPPED, I would rather have gradle consider that if the protobuf directory already exists, the task is UP-TO-DATE. How can this be done?

Instead of enable/disable a task, please register a task output, then gradle will be aware itself if a task is up-to-date or not. Please have a look at the example below which you can find helpful:

task mk(type: Exec) {
  def output = project.file('mk')
  outputs.dir output
  commandLine 'mkdir', output
  workingDir '.'
}

If you run gradle mk twice, the task will execute only once.
