project root
modelVersion - should be set to 4.0.0
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
Here's an example:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.juvenxu.mvnbook</groupId>
<artifactId>hello-world</artifactId>
<version>1.0-SNAPSHOT</version>
</project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.juvenxu.mvnbook</groupId>
<artifactId>hello-world</artifactId>
<version>1.0-SNAPSHOT</version>
</project>
A POM requires that its groupId, artifactId, and version be configured. These three values form the project's fully qualified artifact name.
