Multiple errors on startup when attempting to integrate Atmosphere
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!
I used this example to do it.
Notable things:
- Main errors:
-
java.lang.NoSuchMethodError: org.eclipse.jetty.websocket.server.WebSocketServerFactory.<init>(Lorg/eclipse/jetty/websocket/api/WebSocketPolicy;)V -
java.lang.ClassNotFoundException: org.eclipse.jetty.continuation.ContinuationListener
-
- I have
containerin 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 https://github.com/Atmosphere/atmosphere/issues/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
