I'm trying to run the mqtt-example in Java, it ran succesfully in Intellij IDEA but failed when using command line vertx.

The console kept reporting errors of not finding mqtt libraries as below. I've tested running it in console in Groovy, js and Kotlin, but got pretty much the same errors everywhere. What should be done to get it go?


vertx-examples/mqtt-examples/src/main/java/io/vertx/example/mqtt/app/Client.java:19: error: package io.netty.handler.codec.mqtt does not exist
import io.netty.handler.codec.mqtt.MqttQoS;
 
mqtt-examples/src/main/java/io/vertx/example/mqtt/app/Client.java:24: error: package io.vertx.mqtt does not exist
import io.vertx.mqtt.MqttClient;

can you check that it is enabled in the vertx-stack.json file of your CLI distribution ?

My guess is no:

$ vertx resolve --dir=lib
Error while executing command resolve: Cannot find the stack descriptor. Have been tried:
     - .//usr/local/Cellar/vert.x/3.5.0/libexec/vertx-stack.json
     - /usr/local/Cellar/vert.x/3.5.0/libexec/vertx-stack.json

I used vanilla vertx-example and vanilla Homebrew vertx-3.5.0. Are there more pointers to configure this mqtt-example out-of-the-box?

Hi Julien,

After some tweaking, I can confirm that vertx-mqtt is now enabled in my vertx-stack.json. And "$vertx resolve" reported no errors.

But I'm still getting the following error when running mqtt-example in CLI:

$ vertx run server.js

this looks like javascript support is not enabled in the stack

Yes Alexander that was indeed the case, thank you. However, I've enabled javascript in the vertx-stack, but the JS/groovy/Kotlin error proceeds to something like this:

$ vertx run server.js

meanwhile in another term I opened the client:


$ vertx run client.js

Then the server side initially ran all right, waiting for client requests. But the moment I power up the client, the server gave the following error:
