What is the main feature of a POM file and why is it actually used?
How will the dependencies get mapped to the Java virtual machine whatever we give in it and become flexible on application?

POM is an XML file that contains the project configuration details used by Maven. It provides all the configurations required for a project. POM means Project Object Model, and, as the name suggests, it defines the model of the project as well.
pom. xml is required for building project using Maven. You might import jars manually in eclipse but for building the project in some other build system which supports Maven, you would need pom.
Under this directory you will notice the following standard project structure. The src/main/java directory contains the project source code, the src/test/java directory contains the test source, and the pom. xml file is the project's Project Object Model, or POM.
The pom. xml is placed in the projects root-folder.
A Project Object Model or POM is the fundamental unit of work in Maven. It is an XML file that contains information about the project and configuration details used by Maven to build the project. It contains default values for most projects. Examples for this is the build directory, which is target; the source directory, which is src/main/java; the test source directory, which is src/main/test; and so on.
The POM was renamed from project.xml in Maven 1 to pom.xml in Maven 2. Instead of having a maven.xml file that contains the goals that can be executed, the goals or plugins are now configured in the pom.xml. When executing a task or goal, Maven looks for the POM in the current directory. It reads the POM, gets the needed configuration information, then executes the goal.
