jeroenr / akka-http-docker-sample Goto Github PK

I am following your blog post located at https://medium.com/jeroen-rosenberg/lightweight-docker-containers-for-scala-apps-11b99cf1a666

After starting a new sbt project using the recommended command
sbt -Dsbt.version=0.13.15 new https://github.com/akka/akka-http-scala-seed.g8

It successfully applies the template:
name [My Akka HTTP Project]: hello-world
scala_version [2.12.3]:
akka_http_version [10.0.9]:
akka_version [2.5.3]:
organization [com.example]:
Template applied in ./hello-world

I then try to start the service using
sbt "runMain com.example.WebServerHttpApp"

but this yields error that it cannot find the specified class:
[error] (run-main-0) java.lang.ClassNotFoundException: com.example.WebServerHttpApp
java.lang.ClassNotFoundException: com.example.WebServerHttpApp

Inspecting the src folder, indeed there is no package named com.example and all code appears to be under the package com.lightbend.akka.http.sample which contains 4 files, none of which are named WebServerHttpApp, and the one that seems to be a main-looking file is called QuickstartServer.scala but this does not have a Main method.

Perhaps the giter8 template has dramatically changed since the blog post 10 days ago? Interestingly, opening https://github.com/akka/akka-http-scala-seed.g8 in a browser redirects to https://github.com/akka/akka-http-quickstart-scala.g8

In case it matters, I am running Ubuntu 16.04 with sbt 0.13.15
