a.   Download maven

b.   Setting up JAVA_HOME

c.    Setting up maven environment

d.   Verify maven installation

Download maven

Download maven from below location.

https://maven.apache.org/download.cgi

At the time of writing this article, 3.5.3 is the latest version of the maven software.

Setting up maven in your system

Extract the downloaded maven software.

Once you extract the downloaded zip, file, you can see above kind of folder structure. All the maven executables will be located in ‘bin’ directory.

Since Maven 3.3+ require JDK 1.7 or above to execute, you need to setup java run time environment in your system.

Following post can help you in setting up the java environment.

Set JAVA_HOME environment variable to the base directory of java installed location.

Setting up JAVA_HOME

Setting JAVA_HOME in windows

Right click on my computer -> properties.

Click on ‘Advanced system settings’.

Go to Advanced tab and click on ‘Environment Variables’ button.

In the System variables section, click on ‘New’ button.

Give the variable name as ‘JAVA_HOME’ and value to the location (For ex: C:\Program Files (x86)\Java\jdk1.8.0_102), where java is installed in your machine. Press Ok button.

That’s it you are done….:)

Setting JAVA_HOME in Linux Environment

Korn and bash shells:

export JAVA_HOME=jdk-install-dir

Bourne shell:

JAVA_HOME=jdk-install-dir

export JAVA_HOME

C shell:

setenv JAVA_HOME jdk-install-dir

For example, in Windows, you can check whether JAVA_HOME set or not, by executing below command.

C:\>echo %JAVA_HOME%

C:\Program Files\Java\jdk1.8.0_102

You should append <JAVA_HOME>/bin path to the system path.

Once everything is done, open command prompt (or) terminal. Execute the command ‘javac -version’.

C:\>javac -version

javac 1.8.0_102

If you can see above kind of output, your java installation is successful.

Setting up maven environment

We need to set maven home (M2_HOME), M2 and maven options (MAVEN_OPTS) environment variables.

In my case, I set the maven environment variables like below.

M2_HOME=C:\Users\krishna\Documents\softwares\Maven\apache-maven-3.5.3

M2 = %M2_HOME%\bin

MAVEN_OPTS=-Xms256m -Xmx512m

Add maven bin directory path to the system path.

On Windows       

Append the string ;%M2% to the end of the system variable, Path.

On Linux environment

export PATH=$M2:$PATH

Verify maven installation

Open command prompt (or) terminal and execute the command ‘mvn -version’.

If you are able to see below kind of output, then your maven setup is correct.

C:\>mvn -version
C:\
Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-25T01:19:05+05:30)
