Hi, I'll be little bit detailed here.

I need to use this module. I put this line into mod.json

"deploys": "io.vertx~lang-scala_2.10~1.1.0-M1,io.vertx~mod-mysql-postgresql_2.10~0.3.1"

I have this in langs.properties:

scala=io.vertx~lang-scala_2.10~1.1.0-M1:org.vertx.scala.platform.impl.ScalaVerticleFactory

What I am doing here is that I am adding this module to deployments hence when I run my fat jar, it will automatically use this plugin.

Then I have my main verticle in which I am deploying this module

container.deployModule("io.vertx~mod-mysql-postgresql_2.10~0.3.1",
    new Handler<AsyncResult<String>>() {

    @Override
    public void handle(AsyncResult<String> event) {
        if (event.succeeded()) {
            System.out.println("succeeded");
        } else {
            System.out.println("not succeeded");
            System.out.println(event.cause().getMessage());
        }
    }
});

So it does this: http://pastebin.com/CJ5fjy7X

The bad thing is that this occurs randomly. Once it runs ok, once it fails with that ouptup.

Things I do not understand:

1. Why it downloads scala module even I have bundled it into fat jar? I can see that module in mods dir in fat jar but when I start it, it downloads it every time. I have pulled in all dependencies into fat jar hence I do not see any reason why it should download them all over again.
2. It downloads it EVERY TIME even I do have it in VERTX_HOME/sys-mods directory as it is system module
3. It downloads it EVERY TIME even I do have that scala module in VERTX_MODS directory.
4. Why it fails to deploy it and that promise error is there?

I am using Java 1.8

Is there any recomanded way how to use this module in my runnable vert.x module?

Thanks!
