How To Install Apache Maven on Ubuntu 20.04 LTS

In this tutorial, we will show you how to install Apache Maven on Ubuntu 20.04 LTS. For those of you who didn’t know, Apache Maven is an open-source project management and comprehension tool used primarily for Java projects. Maven uses a Project Object Model (POM), which is essentially an XML file containing information about the project, configuration details, the project’s dependencies, and more.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Apache Maven’s open-source data visualization and monitoring suite on a 20.04 LTS (Focal Fossa).

Prerequisites

• A server running one of the following operating systems: Ubuntu 20.04, 18.04, and any other Debian-based distribution like Linux Mint.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, you can harm your system if you’re not careful when acting as the root.

Install Apache Maven on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Installing Java.

Apache Maven requires JDK 1.7 or above to be installed. To install Java run the following command:

sudo apt install default-jdk

Verify the Java version by running the following command:

java -version

Step 3. Installing Apache Maven on Ubuntu 20.04.

The first thing to do is to go to Apache Maven’s download page and download the latest stable version of Apache Maven, At the moment of writing this article it is version 3.6.3:

wget https://www-us.apache.org/dist/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz -P /tmp

After that, extract the downloaded archive using the following command:

sudo tar xf /tmp/apache-maven-*.tar.gz -C /opt
sudo ln -s /opt/apache-maven-3.6.3 /opt/maven

Step 4. Setup Environment Variables.

Next, we’ll need to set up the environment variables by creating a new file /etc/profile.d/maven.sh:

sudo nano /etc/profile.d/maven.sh

Add the following content:

export JAVA_HOME=/usr/lib/jvm/default-java
export M2_HOME=/opt/maven
export MAVEN_HOME=/opt/maven
export PATH=${M2_HOME}/bin:${PATH}

Finally, load the environment variables using the source command:

sudo chmod +x /etc/profile.d/maven.sh
source maven.sh

Step 5. Verify Installation.

Once everything has been successfully configured, check the version of the Apache Maven:

$ mvn -version
