To install Apache Maven &ndash 3.3.9 on Linux mint &ndash 18.3

Apache Maven is a project management tool for managing the building, reporting and documenting of Java-based development project. It contains a project object model, a set of standards, a project lifecycle, a dependency management system and logic. Maven is designed to provide a sample project setup for users to have an easy environment.Maven addresses two parts of building a software, first, it describes how a software is built and second its dependencies. This tutorial covers the installation procedure of Apache Maven on Linux mint &ndash 18.3.

Installing Apache Maven

First, update the system repository by making use of the following command. 

linuxhelp user # apt-get update

And once it is done, you need to add the repository by running the following command. 

linuxhelp user # add-apt-repository ppa:webupd8team/java
You are about to add the following PPA:
 Oracle Java (JDK) Installer (automatically downloads and installs Oracle JDK7 / JDK8 / JDK9). There are no actual Java files in this PPA.
Important ->  Why Oracle Java 7 And 6 Installers No Longer Work: http://www.webupd8.org/2017/06/why-oracle-java-7-and-6-installers-no.html

Ubuntu 16.10 Yakkety Yak is no longer supported by Canonical (and thus, Launchpad and this PPA). The PPA supports Ubuntu 17.10, 17.04, 16.04, 14.04 and 12.04.

Once again, you need to update the system repository by making use of the following command. 

linuxhelp user # apt-get update

You shall now proceed with the installation of Oracle Java by making use of the following command. 

linuxhelp user # apt-get install oracle-java8-installer

Oracle JDK 8 installed

#####Important########
To set Oracle JDK8 as default, install the " oracle-java8-set-default"  package.
E.g.: sudo apt install oracle-java8-set-default
On Ubuntu systems, oracle-java8-set-default is most probably installed
automatically with this package.

You shall now check java version by making use of the following command. 

linuxhelp user # java -version
java version " 1.8.0_161" 
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

And then, you need to change the directory. 

linuxhelp user # cd /opt/

You shall now download the package of apache maven by running the following command. 

linuxhelp opt # wget http://www-eu.apache.org/dist/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz
--2018-03-20 14:30:25--  http://www-eu.apache.org/dist/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz

And then you need to extract the packages by making use of the following command. 

linuxhelp opt # tar -zxvf apache-maven-3.3.9-bin.tar.gz 
apache-maven-3.3.9/boot/plexus-classworlds-2.5.2.jar
apache-maven-3.3.9/lib/maven-embedder-3.3.9.jar
apache-maven-3.3.9/lib/maven-settings-3.3.9.jar
apache-maven-3.3.9/lib/plexus-utils-3.0.22.jar

.
.
apache-maven-3.3.9/conf/
apache-maven-3.3.9/conf/logging/
apache-maven-3.3.9/conf/logging/simplelogger.properties
apache-maven-3.3.9/conf/settings.xml
apache-maven-3.3.9/conf/toolchains.xml
apache-maven-3.3.9/lib/ext/
apache-maven-3.3.9/lib/ext/README.txt

You can now list out the file.

linuxhelp opt # ls
apache-maven-3.3.9   apache-maven-3.3.9-bin.tar.gz

Then, you need to rename the extracted file.

linuxhelp opt # mv apache-maven-3.3.9 maven

You need to set an environment variable for Maven. Open the file. 

linuxhelp opt # vim /etc/profile.d/mavenenv.sh 

And add the following lines to it.

[..]
#!/bin/bash
MAVEN_HOME=/opt/maven
PATH=$MAVEN_HOME/bin:$PATH
export PATH MAVEN_HOME
export CLASSPATH=.
[..]

After that, you need to make the executable for environment file.

linuxhelp opt # chmod +x /etc/profile.d/mavenenv.sh 

Next, you need to set the  environment variables  permanently. 

linuxhelp opt # source /etc/profile.d/mavenenv.sh 

Afterward, you need to check the maven version by making use of the following command. 

linuxhelp opt # mvn -version
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5  2015-11-10T22:11:47+05:30)
Maven home: /opt/maven
Java version: 1.8.0_161, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-8-oracle/jre
Default locale: en_IN, platform encoding: UTF-8
OS name: " linux" , version: " 4.10.0-38-generic" , arch: " amd64" , family: " unix" 

If you want to check the  path  and  environment variables 

linuxhelp opt # echo $MAVEN_HOME
/opt/maven
linuxhelp opt # echo $PATH
/opt/maven/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

With this, the tutorial comes to an end.
