QUESTION
I'm running the hivemq mqtt broker community edition and wanted to add the prometheus extension for monitoring.
Both come precompiled from the hivemq marketplace and the github project page.
I download both components as a zip file, unzip them and copy them into a java 11 docker container using this dockerfile:

Answered 2019-Jul-24 at 15:24Actually no dependency from the hivemq broker community edition contains ServletContextListener. I downloaded the source code from github and modified the build.gradle file.
Add the last line of the following snippet to the build.gradle file:

QUESTION
I was using HiveMQ Client version 1.0.1 but I decided to update to the recently released version 1.1. I completely started from scratch and imported the project as a Gradle project and tried to build. The build work only after ignoring a few failed tests. I'm getting 3 errors in 3 different classes. I realize this is likely related to the Dagger dependency injection tool and I had already successfully built the project and added the directory of build/generated/source/apt/main/
to my build path as noted by my previous stack post where I had issues with a DaggerSingletonComponent not being found: How to fix DaggerSingletonComponent not resolved in HiveMQ (MQTT protocol) . This seems to be a new issue and I'm not sure what's wrong. I tried rebuilding by project but the errors still persist. I've left some screenshot below as well as the specific errors.

Answered 2019-Jun-14 at 14:11Executing ./gradlew clean build
on the command line will fix your error.
But I also think that the real solution for your use case is to create a new empty project (gradle or maven) and add the client library as a dependency, like described here: https://hivemq.github.io/hivemq-mqtt-client/docs/installation.html
QUESTION
I'm writing a main class that will create a few clients and test them subscribing and publishing. I'd like to display information of the clients connection, like the data & time connected, clientId, clientIP used to connect, whether they connected gracefully or not. I'm new to using tools like Logger so I'm not sure how I would do this. I left a link to the HiveMQ community edition (broker) and the client. I'd like to display this information in my main class in the HiveMQ client project but there a log file in the community edition called event.log which contains exactly the kind of information I want to display. I left an image below.

There is an event.log file in hivemq-community-edition that has the kind of information I'd like to display. It was generated when I build the project as a Gradle project so it won't be found unless you imported into Eclipse and built in with Gradle so I left a screenshot of what it looks like.

No. There is no such thing in MQTT as "give me a list of all topics in a broker".
Your code can subscribe to all "active" topics but that does mean you will capture all of the topics unless you leave your code running 7/24 for months or years.
Simply change your subscription to the following:
QUESTION
I'd like to combine HiveMQ Client and HiveMQ Community Edition which is the implementation for the broker into one project. I tried adding the HiveMQ client as a dependency to the build.gradle file in the Hive MQ Community Edition (broker). It was able to build successfully but I'm not sure if I did it correctly. When I tried to reference client classes inside the Community Edition it gives me errors. Am I missing something? I want to be able to just put put the client project inside of the broker community edition and be able to create a client and access all of the classes I could in HiveMQ client. I left the instructions from the HiveMQ Client website, links, and also what the build.gradle file looks like the HiveMQ community edition.
Error I'm getting: The import com.hivemq.client cannot be resolved (Happens to all imports referencing anything in the HiveMQ Client project)
