  // Excluded Controller because spotless is making it very hard to read.
  exclude '/Controller.java'
  })
  }

Any plan to fix this?

This is perhaps related to FasterXML/jackson-dataformats-text#36 and in the end SnakeYaml?

This is really unfortunate bug, I am considering the removal of yaml step because of it.

@henrikcaesar SnakeYAML supports the comments.

+100 for fix.i lost a lot of info when running this....

The lack of proper comments management in yaml was initially discussed in #910, and discussed with Jackson team in FasterXML/jackson-dataformats-text#372, itself referring FasterXML/jackson-dataformats-text#36 which is still open and active.

One may consider contributing a SnakeYAML linter (vs current Jackson linter, based on SnakeYAML).
