Maven - Anatomy of the pom.xml file
The pom.xml is the Project Object Model, a declarative XML document that describes the build and it’s dependencies.
There’s little need to reproduce the information published in the Maven POM reference https://maven.apache.org/pom.html#Introduction

\centering Most of this is optional or only applies under certain circumstances, and Maven gives clear messages when something has been left out. It also gives warnings if something isn’t needed or conflicts with parent POM declarations, so pay attention to the output from your build processes.
