First of all download the maven tar into the environment. Below I have show the command to download maven 3.5.0

wget https://archive.apache.org/dist/maven/maven-3/3.5.0/binaries/apache-maven-3.5.0-bin.tar.gz

Now Apache maven tar binary will be downloaded to where you execute above command. Then untar the binary file using below command

tar -xvf apache-maven-3.5.0-bin.tar.gz

Now we are going to set up maven for you. You can copy unzipped folder to where ever you want it to be. My case I will create a folder called usersettings and move the maven folder into usersettings folder.

Now need to set up path variables for M2_HOME and M2 variables like below

export M2_HOME=/home/ec2-user/usersettings/apache-maven-3.5.0
export M2=$M2_HOME/bin
And attach JVM memory for maven process like below
export MAVEN_OPTS=-Xmx1024m

Now you are ready to go and you can just type mvn -version or mvn to test maven successfully set up on your environment
