[SOLVED] No engine found

No engine found - PredictionIO

No engine found error when using the below Scala template, http://predictionio.incubator.apache.org/templates/complementarypurchase/quickstart/

I have the correct Scala version,

scala -version
Scala code runner version 2.11.8 -- Copyright 2002-2016, LAMP/EPFL

From template build.sbt

scalaVersion := "2.11.8"
