How to Install Apache Maven 3.5 on CentOS 7

Apache Maven is a free and open source software project management tool which is widely used for deploying Java-based applications.

Prerequisites

• A newly deployed Vultr CentOS 7 x64 server instance.

• A sudo user.

• The server instance has been updated to the latest stable status.

Step 1: Install OpenJDK 8

Apache Maven requires Java 1.7 or greater. For this reason, you can install OpenJDK 8 as follows.

sudo yum install -y java-1.8.0-openjdk-devel

Having OpenJDK 8 installed, use the command below to verify the result.

java -version

If all went well, the output should be similar to this.

openjdk version "1.8.0_141"

OpenJDK Runtime Environment (build 1.8.0_141-b16)

OpenJDK 64-Bit Server VM (build 25.141-b16, mixed mode)

Finally, setup the JAVA_HOME environment variable.

echo "JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")" | sudo tee -a /etc/profile

source /etc/profile

Step 2: Install Apache Maven 3.5

First, download and extract the Apache Maven 3.5 archive.

cd

wget http://www-us.apache.org/dist/maven/maven-3/3.5.0/binaries/apache-maven-3.5.0-bin.tar.gz

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

Move all Apache Maven 3.5 files to a reasonable location and change their ownership to root:root:

sudo mv ~/apache-maven-3.5.0 /opt

sudo chown -R root:root /opt/apache-maven-3.5.0

Create a version-irrelevant symbolic link pointing to the original Apache Maven 3.5 directory.

sudo ln -s /opt/apache-maven-3.5.0 /opt/apache-maven

Add the path /opt/apache-maven to the PATH environment variable.

echo 'export PATH=$PATH:/opt/apache-maven/bin' | sudo tee -a /etc/profile

source /etc/profile

Finally, use the command below to verify the installation.

mvn --version

The output should resemble the following.
