  • Did you solve your problem? I see someone had similar issue in the past and one of answers was upgrading sbt https://stackoverflow.com/a/60118115/4099089 I would try it. – michaJlS Jul 14 '20 at 16:37
  • No I'm not able to solve it. I'm creating a predictionIO recommendation engine and While building the app it crashes and throws the above error. Do you have any idea how to upgrade sbt version in the predictionIO setup? – Anoop Sharma Jul 15 '20 at 11:08
