Après avoir suivi le quickstart (pour la version 0.11.1) sur https://predictionio.incubator.apache.org/templates/recommendation/quickstart/, je n'arrive pas à créer le template/engine (j'ai essayé de construire MyRecommendation et un autre template NLP). pio build --verbose se termine par:Prédiction IO: construction, pas de moteur trouvé
[INFO] [Engine$] Compilation finished successfully.
[INFO] [Engine$] Looking for an engine...
[ERROR] [Engine$] No engine found. Your build might have failed. Aborting.
Lorsque je tente de lancer pio train il échoue avec:
Exception in thread "main" scala.ScalaReflectionException: object org.example.recommendation.RecommendationEngine not found.
L'auditeur est en cours d'exécution ok (les données peuvent également être tiré par boucle), pio status:
