Maven POM Concepts

Each project has a corresponding Project Object Model or POM file that is located in the root directory. Whenever a goal (a specific build task) has to be executed, Maven looks for the configuration details in POM.

• Project details can be represented in the form of XML file called pom.xml.
• It is the fundamental unit that contains information about the project.
• It holds all the resources required for a build such as source code location, test source, dependency details such as external or internal dependency etc.

POM.xml takes minimal coordinate attributes as inputs for the project as groupId:artifactId:version.

POM stores the information such as the location of the source code and records any external dependencies. It describes what needs to be built as part of the project.
