Please click this link to see the exact log i am seeing after running pio build. It fails as it can't find engine. Help would be much appreciated
回答1:
I meet the same problem, because I specified scala.version=2.11.8 when I build PredictionIO but the engine template I used was build with scala 2.10.
so I edit build.sbt file under engine's folder, and add scalaVersion := "2.11.8", re-run the build command(pio build --verbose), then everything build finished successfully.

Check which version of scala you are using in the engine's build.sbt version and make sure you use that version when you build from source like this:
./make-distribution.sh -Dscala.version=<PUT CORRECT SCALA VERSION HERE> -Dspark.version=2.1.0 -Delasticsearch.version=2.3.3
