> The build command does not fail as expected. While not a big deal when working locally, it seems like this could be problematic for automated, continuous build/integration workflows.

> [ERROR] [Engine$] [error] one error found
> [ERROR] [Engine$] [error] (compile:compileIncremental) Compilation failed
> [ERROR] [Engine$] [error] Total time: 5 s, completed Jun 21, 2017 9:59:55 AM
> [ERROR] [Engine$] Return code of build command: /Users/mars.hall/Projects/predictionio-engine-ur/PredictionIO-dist/sbt/sbt  package assemblyPackageDependency is 1. Aborting.

> It certainly appears successful at the end, and exit code was {{0}}.
> Looking back for the error is not hard, but this behavior is problematic when composing {{pio build}} command into a shell script.
