Subject Re: [ERROR] [Engine$] No engine found. Your build might have failed. Aborting. - using PredictionIO-0.11.0-incubating scala.version=2.11.6 spark.version=2.1.0 elasticsearch.version=2.3.3

Donald.. thanks.  genius and so simple.  I didn't understand your
suggestion yesterday when I opened the issue.  It worked
for incubator-predictionio-template-attribute-based-classifier.  I'm still
working to get the old LDA engine working.. suspect that's going to take a
little more work.

Here is the build.sbt that worked for
incubator-predictionio-template-attribute-based-classifier

import AssemblyKeys._

assemblySettings

name := "template-scala-parallel-classification"

organization := "org.apache.predictionio"

scalaVersion := "2.11.6"

libraryDependencies ++= Seq(
  "org.apache.predictionio" %% "apache-predictionio-core" %
"0.11.0-incubating" % "provided",
  "org.apache.spark"        %% "spark-core"               % "1.3.1" %
"provided",
  "org.apache.spark"        %% "spark-mllib"              % "1.3.1" %
"provided")

Barthe.
