mvn verify
Maven generate shaded jar: myproject-1.0-SNAPSHOT-shaded.jar
Nice.
Them I copy jar to separate folder I try to start jar like this:

But I get error:

In my code AppStarter I try to start server:
import org.eclipse.jetty.server.Server
import org.eclipse.jetty.server.handler.HandlerList
import org.eclipse.jetty.server.handler.ResourceHandler
val server = Server(port)
server.handler = handlers
server.start() // error here
server.join()

Answer 1

This can be the atmosphere not detecting the new Jetty version websocket support and trying to use the old server specific implementation.
You can for the JSR356 by adding a init parameter:
<init-param>
<param-name>org.atmosphere.cpr.asyncSupport</param-name>
<param-value>org.atmosphere.container.JSR356AsyncSupport</param-value>
</init-param>
Or in annotation:
#WebInitParam (
name = org.atmosphere.cpr.asyncSupport,
value = org.atmosphere.container.JSR356AsyncSupport
)

Answer 2

Same problem here, added the params under ../WEB-INF/web.xml for the expanded web app, but nothing ...
Using latest jetty 9.4.20 and vaadin 14.0.5

Answer 3

org/eclipse/jetty/websocket/WebSocketFactory$Acceptor is part of Jetty 8 or below
Either upgrade to new Jetty 9 WebSocket API or degrade your libraries to jetty 8
