Maven is one of the most powerful tools I've ever seen, and thus has a bunch of features embedded. If you are new to it, check out this reference:

The most important file in a Maven-based project is the pom.xml (POM stands for Project Object Model). For example, when you create a new Java EE 8 project, it should look like this:
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.eldermoraes</groupId> <artifactId>javaee8-project-template</artifactId> ...
