Jetty v11 missing HttpMethod
What issue? Are you using the official version of Traccar? You have to provide much more context of you want some help.
I'm on branch master and the ide show me this error for jettyVersion = "11.0.19"
You probably need to clear the cache and indexes in your IDE.
The version of Jetty has been upgraded from 10.0.15 to 11.0.19, and now there is an issue with the WebServer class because HttpMethod is not present in Jetty 11.
