Unable to compile akka-sample-kafka-to-sharding-scala project in my local

Hi Team,

I am trying to setup akka-sample-kafka-to-sharding-scala project in my local and but I am getting an error saying
sample.sharding.kafka.UserServiceClient
sample.sharding.kafka.UserStatsRequest

Is missing. I have tried downloading from lightbend as well but still not able to compile the code.

Thanks
