>From my understanding of the binary compatibility statement, these should
work together, but after I start an Akka-http server, I get this exception:
java.lang.NoSuchMethodError:
akka.actor.ActorCell.addFunctionRef(Lscala/Function2;)Lakka/actor/FunctionRef;
at akka.stream.stage.GraphStageLogic$StageActor.<init>(GraphStage.scala:142)
at akka.stream.stage.GraphStageLogic.getStageActor(GraphStage.scala:929)
...
Now, I'm starting this from inside an actor, but didn't think that would be
an issue. I've tried starting the Http server from main(), but it throws
the same exception. To start it, I'm doing this:
ActorSystem system = getContext().system();
final HttpBinding myServer = new HttpBinding();
myServer.startServer("localhost", 8080, ServerSettings.create(system), system);
The HttpBinding class is:
public class HttpBinding extends HttpApp {
protected Route route() {
return path("hello", () ->
get(() ->
complete("<h1>Say hello to akka-http</h1>")
)
);
}
}
I've checked the dependencies, and nothing's brought in an older version of
akka. I'm using the Scala 2.12 versions of everything. From my build.gradle:
compile group: 'com.typesafe.akka', name: 'akka-actor_2.12', version: '2.5-M2'
compile group: 'com.typesafe.akka', name: 'akka-persistence_2.12', version:
'2.5-M2'
compile group: 'com.typesafe.akka', name: 'akka-slf4j_2.12', version: '2.5-M2'
compile group: 'com.typesafe.akka', name: 'akka-http_2.12', version: '10.0.4'
The only place I've seen a similar exception discussed was a StackOverflow
question that involved Play, and I'm not using Play. Any suggestions on
where to look for the problem? Or should I just wait for the final release of
Akka 2.5 and Akka-Http to catch up?
Thanks!
