Maven: print tree representation of maven dependencies


'mvn dependency:tree' command prints all the dependencies in tree format.

For example, consider below pom file.

pom.xml
<project>
   <modelVersion>4.0.0</modelVersion>
   <groupId>org.selflearningjava</groupId>
   <artifactId>rootWebPom</artifactId>
   <packaging>pom</packaging>
   <version>1</version>
   
   <name>Root pom for all the web application</name>

 <dependencies> 
 
  <dependency>
   <groupId>junit</groupId>
   <artifactId>junit</artifactId>
   <version>${junit.version}</version>
   <scope>test</scope>
  </dependency>
  
  <dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-core</artifactId>
   <version>${hibernate.version}</version>
  </dependency>

  <dependency>
   <groupId>org.glassfish.jersey.core</groupId>
   <artifactId>jersey-server</artifactId>
   <version>${jersey.version}</version>
  </dependency>

 </dependencies>
   
   <properties>
  <junit.version>4.12</junit.version>
  <hibernate.version>5.2.16.Final</hibernate.version>
  <jersey.version>2.27</jersey.version>
   </properties>
   
</project>


Go the the directory, where the pom file is located and execute the command 'mvn dependency:tree', you will see below kind of output.
