Using Apache Maven we can do the following tasks:

• extract source code
• build the package
• deploy to target
• test the application basic sanity

The trending build tool for Java enterprise level Projects, it works based on 'pom.xml' file a Project Object Model (POM). The greatest advantage of Maven is plugin support for libraries. 

Install Maven

There are two basic distributions of Maven installers: binary and source archives. If you need the installation should be done quick then use the binary installer, where you need simple extraction of archives. On the other hand, source archives will take time and three steps you need to follow: configure, make and make install. So here I am selecting the first method - binary archive installation.

Tip: Always visit the maven official site where you can find the latest version archives.

Prerequisites:

• Your machine must have archiving tools to extract the maven installers. There are 4 downloads choices for maven. 
• Any JRE (Oracle JRE/OpenJRE) must be installed

Steps-by-Step Maven 3 installation 

Step 1: First download in /tmp, Then, navigate where you want to install the maven build tool.

cd /tmp
wget http://mirrors.estointernet.in/apache/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz

Step 2: Now installation directory

[root@mydev tmp]# cd /opt
[root@mydev opt]# tar -zxvf /tmp/apache-maven-3.6.1-bin.tar.gz
ln -s apache-maven-3.6.1 maven

Best Practice: To make more easy to use the maven installation path soft link created and the same will be used in the environment setup. Step 3: Set the Environment variables in the common profile location

vi /etc/profile.d/maven.sh

#Maven environment setting
export M3_HOME=/opt/maven
export PATH=$M3_HOME/bin:$PATH

Save this Maven environment setting file.

Verify the installation

Step 4: Verify the Maven installation in different users:

 mvn --version

This will give you the four things: Maven Path, Java vendor, JRE Path, Default locale, OS related full details.

First root user, where Open JRE in use

mvn run from root user

 Next switch to 'oracle' user where Oracle JRE in use.
