Router issues with Vertx
<p>Good morning, 
I begin with Vertx for java and I want to create the route example so I copy past the lines but it seems there is something wrong in Router.router(vertex) : </p>

<blockquote>
  <ul>
  <li><p>The type io.vertx.rxjava.core.Vertx cannot be resolved. It is indirectly referenced from 
   required .class files</p>
  
  <ul>
  <li>The method router(Vertx) from the type Router refers to the missing type Vertx</li>
  </ul></li>
  </ul>
</blockquote>

<p>Here is my code : </p>

<pre><code>import io.vertx.core.*;
import io.vertx.rxjava.ext.web.*;
import io.vertx.core.http.HttpHeaders;

public class Test extends AbstractVerticle{

@Override
public void start() throws Exception {

    Vertx vertx=Vertx.vertx();
    Router router = Router.router(vertx);

    Route route1 = router.route("localhost:8080/Orsys/").handler(routingContext -&gt; {

          HttpServerResponse response = routingContext.response();
          response.setChunked(true);

          response.write("Orsys\n");

          routingContext.vertx().setTimer(5000, tid -&gt; routingContext.next());
        });
</code></pre>
