Hi @washingon!
Based on some responses at PIO incubator mailing list, I managed to solve mine.
Here is what I did. I was adding `scalaVersion := "2.1.0"` and adjust PIO version to `0.11.0-incubating` on failing engine [build.sbt](https://github.com/kahirul/docker-predictionio/commit/d9b28b5aaa4229d38631e9014758640d0380e59d?diff=unified#diff-a2d5a333149e0503d95ee9e8a83c0be6) file. And I can build the engine successfully.

Hi, please redirect usage questions to user@predictionio.incubator.apache.org, and development question to dev@predictionio.incubator.apache.org for more exposure to the rest of the community. Subscription instructions can be found at http://predictionio.incubator.apache.org/support/.
Did you also modify your engine template's Scala version to 2.11.6?

Hi, I'm also experiencing the same issue. I'm trying to build this template https://github.com/apache/incubator-predictionio-template-recommender/tree/v0.4.0
I did modify the engine. Removing `rate` event from `DataSource.scala`
Here are output of `pio status`
