Viewing a POM file after creating a project
Once we have created a project, we can see the pom.xml file in our project folder. It will have all the basic details, such as groupId, name, and so on. Also, you can see the default Junit dependency under the dependencies configuration part:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.packtpub.restapp</groupId>
<artifactId>ticket-management</artifactId>
<packaging>jar</packaging>
<version>1.0-SNAPSHOT</version>
<name>ticket-management</name>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
Maven artifacts belong to a group (typically com.organization.product), and must have a unique identifier.
In the preceding POM file, the SNAPSHOT suffix in version tells Maven that this project is still in development.
