Can you please add a little to README on how to run these examples?
What is the gradle script good for here? It seems out of sync with vertx gradle template.

Because there are no reply handlers in vert.x publish messages.

The following error occurs when checking out the repository and building with gradle.

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all dependencies for configuration ':testRuntime'.
> Could not find io.vertx:vertx-core:2.1M2-SNAPSHOT.
  Required by:
      io.vertx:vertx-examples:1.0.0-SNAPSHOT
> Could not find io.vertx:vertx-platform:2.1M2-SNAPSHOT.
  Required by:
      io.vertx:vertx-examples:1.0.0-SNAPSHOT

The milestone artifact does not exist anymore on Maven Central. Upgrading the dependency version fixes this.

I am getting this problem when running the scala webapp,

Hello,
I've cloned the project and it is empty in netbeans. I've already reported an issue to the gradle-plugin maintainer. However it seems to be an issue with the project structure. Can it be "fixed" so it works in netbeans too?

@see kelemen/netbeans-gradle-project#119

hi...I try to run the echo example (EchoServer.scala) but I get this error:

at java.lang.Thread.run(Thread.java:744)

this code is pretty weird: no imports, no class declared...personally I would feel more confortable writting this in my ide and using sbt for compile and run, is it possible?...I did a try

   import org.vertx.scala.core.net.NetSocket

  import org.vertx.scala.core.streams.Pump

  import org.vertx.scala.platform.Verticle


  object Main extends App with Verticle {
        vertx.createNetServer().connectHandler {
              s: NetSocket =>
                    Pump.createPump(s, s).start()
        }.listen(1234)
   }

but I get tjhe same error....if I try compile it with sbt (NOT RUNNING DIRECTLY WIT VERTX) I get

   info] Compiling 1 Scala source to /home/yo/Downloads/proj/scalavrtx/scalavtx/target   /scala-2.10/classes...
   [warn] Class io.netty.buffer.ByteBuf not found - continuing with a stub.

   [error] Total time: 3 s, completed Jun 13, 2014 8:30:40 PM

I try the javascript example and run perfectly...for the scala compiled example I copy the vertx jar inside my lib (as not managed dependency) and I add the scala version to my sbt file

   libraryDependencies += "io.vertx" % "lang-scala" % "latest.milestone" 

thanks!!

I followed the instructions and ran:

vertx run eventbus_pointtopoint/receiver.rb -cluster
vertx run eventbus_pointtopoint/sender.rb -cluster

Then I only got:

➜  ruby  vertx run eventbus_pointtopoint/receiver.rb -cluster
Starting clustering...
No cluster-host specified so using address 192.168.56.1
Succeeded in deploying verticle

➜  ruby  vertx run eventbus_pointtopoint/sender.rb -cluster
Starting clustering...
No cluster-host specified so using address 192.168.56.1
Succeeded in deploying verticle

But no message received. What am I doing wrong?

I'm investigating this problem for a while and it seems that I cannot communicate different clusters. I start them with -cluster flag, but it seems that they ignore it.

how I could know when all the files have been finished uploading
or how to know how many files are beeing uploading

int fileCount = ??;
int i;
final Object obj = new Object();
req.uploadHandler(new Handler() {
@OverRide
public void handle(HttpServerFileUpload event) {
upload.streamToFileSystem(...);
i++;
if(fileCount == i)
obj.notify();
}
});
synchronized(obj){
obj.wait();
}
//all the files has been finished uploading

I can't get the example working, I'm using the master checkout of Vert.x and of this repo.
The examples are using a non existing method.

Hi,

Let me know if you are interested in adding https://github.com/siddii/vertx-leaderboard project into "vertx-examples"

I'll be more than happy to create a PR.

Cheers!
