Maven (Java) does not build dependencies into a compiled file

Question

Maven (Java) does not build dependencies into a compiled file. Here is the code of my main class, the architecture of the application and the contents of the compiled file.

import club.minnced.discord.webhook.WebhookClientBuilder;

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello!");

        WebhookClientBuilder builder = new WebhookClientBuilder("test");
        System.out.println(builder);
    }
}

The rest:

I read the answers to the questions and ended up making a pom.xml file like this: 12345678901234567890123456789123456789023456789345678945678456789
