Multiple errors on startup when attempting to integrate Atmosphere

[colindean]

I'm really hoping that I've just missed a step somewhere, but I'm having trouble enabling Atmosphere support. I'm new to Scalatra dev as well as Servlet dev and sbt. I've used Scala for ~4 years but have almost never touched sbt!

Logs and examples

I used this example to do it.

Notable things:

1. Main errors:
   1. java.lang.NoSuchMethodError: org.eclipse.jetty.websocket.server.WebSocketServerFactory.<init>(Lorg/eclipse/jetty/websocket/api/WebSocketPolicy;)V
   2. java.lang.ClassNotFoundException: org.eclipse.jetty.continuation.ContinuationListener
2. I have container in the scope for some of my dependencies, when it may not be necessary. I'm quite sure what it means.

I think the problem may be related to Atmosphere/atmosphere#2286 "Jetty Websocket support broken in 2.4.x for Jetty < 9.4", but I'm using Jetty 9.4.6.

I'm not quite sure what to try next beyond setting up the example and slowing bringing in my
few added dependencies.

Here's a diff of the output of show runtime:fullClasspath from within sbt for my project and the example:

The only differences amount to obvious ones:

• introduction of logback and its use of slf4j 1.7.25 instead of 1.7.21
• introduction of semver4j
• introduction of roshttp and its dependencies on monix and reactivestreams
• use of an older version of json4s, which I'll fix presently
