Project Object Model is the basic unit of Maven and defines the project structure, dependencies, etc.
The following are very minimal to create a POM:
modelVersion– should be set to
groupId– the ID of the project's group
artifactId– the ID of the artifact (project)
version– the version of the artifact under the specified group
version are called Maven coordinates and sometimes abbreviated with GAV. They uniquely identify the resulting artifact of a project in a Maven repository (and should do so in the entire universe).
A minimal sample POM looks like:
<project> <modelVersion>4.0.0</modelVersion> <groupId>com.sample</groupId> <artifactId>sample-app</artifactId> <version>0.0.1-SNAPSHOT</version> </project>
