Throw some light on the pom.xml file in Maven.

Here, the full form of POM is project object model. This model consists of all the information about the project. It also consists of the configuration information for the Maven to build the project. It contains the dependencies, build directory, source directory, test source directory, plugin, goals, etc. First the pom.xml file is read and then only the goal is executed. Firstly this pom.xml file was named as project.xml file but after the release of the latest version, it was changed to pom.xml file. There are basically five elements which are used to create a pom.xml file. They are:

• Project
• modelVersion
• groupId
• artifactId
• Version.
