After following the quickstart (for 0.11.1 build) on https://predictionio.incubator.apache.org/templates/recommendation/quickstart/ I'm failing to build the template/engine (I've tried to build both MyRecommendation and another NLP template). pio build --verbose ends with :
[INFO] [Engine$] Compilation finished successfully.
[INFO] [Engine$] Looking for an engine...
[ERROR] [Engine$] No engine found. Your build might have failed. Aborting.
When I try to run pio train it fails with :
Exception in thread "main" scala.ScalaReflectionException: object org.example.recommendation.RecommendationEngine not found.
The listener is running ok (data can be also pulled via curl), pio status :

Any ideas?
