Description

The @Sortable annotation does not appear to support sorting by parent properties, e.g.

Error:(22, 5) Groovyc: Error during @Sortable processing: tried to include unknown property 'name'

Example:

import groovy.transform.Sortable
import groovy.transform.ToString

class SortableSpec {

  static void main(String[] args) {
    new SortableSpec().run()
  }

  void run() {
    Random random = Random.newInstance()

    (0..9).collect {
      new Thing(name: "${random.nextDouble()}")
    }.sort().each { println it }
  }

  static class Base {
    String name
  }

  // @Sortable(includes = 'name') <- fails compilation
  @Sortable
  @ToString(includeSuperProperties = true)
  final static class Thing extends Base {}

}
