Getting error when build and run evaluation metrics

[Kim Trang Le]

Dear all,

I followed this quickstart:

https://docs.prediction.io/templates/classification/quickstart/

and this document for evaluation metrics

https://docs.prediction.io/evaluation/paramtuning/

Everything seems ok until the step build and run evaluation metrics

pio eval org.template.classification.AccuracyEvaluation \
    org.template.classification.EngineParamsList 

I am getting the exception:

Exception in thread "main" scala.reflect.internal.MissingRequirementError: object org.template.classification.AccuracyEvaluation not found.
	at scala.reflect.internal.MissingRequirementError$.signal(MissingRequirementError.scala:16)
	at scala.reflect.internal.MissingRequirementError$.notFound(MissingRequirementError.scala:17)

	at io.prediction.workflow.CreateWorkflow$$anonfun$19.apply(CreateWorkflow.scala:146)

Could anyone help me with this?

Thank you very much.
