How to Install Apache Maven on Ubuntu 20.04

What is Apache Maven?

Apache Maven is a powerful project management tool that is based on POM (Project Object Model). Maven uses a POM, which is essentially an XML file containing information about the project, configuration details, the project’s dependencies, and more. It is used for projects build, dependency and documentation. It simplifies the build process like ANT. But it is too much advanced than ANT. In short terms we can tell maven is a tool that can be used for building and managing any Java-based project. maven make the day-to-day work of Java developers easier and generally help with the comprehension of any Java-based project.

In this tutorial, we will show you two different ways to install Apache Maven on Ubuntu 20.04.

The official Ubuntu repositories contain Maven packages that can be installed with the apt package manager. This is the easiest way to install Maven on Ubuntu. However, the version included in the repositories may lag behind the latest version of Maven.

To install the latest version of Maven, follow the instructions provided in the second part of this article that shows how to download the binary distribution archive from their official website.

Choose the installation method that is most appropriate for your setup and environment. The instructions assume that you are logged in as root or user with sudo privileges.

Installing Apache Maven on Ubuntu 20.04 with apt

Installing Maven on Ubuntu using apt is a simple, straightforward process.

Update the package index and install Maven by entering the following commands:

sudo apt update
sudo apt install maven

To verify the installation, run mvn -version

mvn -version

The output should look something like this:

Apache Maven 3.6.3
Maven home: /usr/share/maven
Java version: 11.0.7, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "5.4.0-26-generic", arch: "amd64", family: "unix"

That’s it. Maven is now installed on your system, and you can start using it.

Installing the Latest Release of Apache Maven

In this section, we’ll provide a step by step instructions about how to download and install the latest Apache Maven version on Ubuntu 20.04.

1. Install OpenJDK

Maven 3.3+ requires JDK 1.7 or above to be installed.

Install OpenJDK 11, by typing:

sudo apt update
sudo apt install default-jdk

Verify the installation by running the following command:

java -version

The output should look something like this:

openjdk version "11.0.7" 2020-04-14
OpenJDK Runtime Environment (build 11.0.7+10-post-Ubuntu-3ubuntu1)
OpenJDK 64-Bit Server VM (build 11.0.7+10-post-Ubuntu-3ubuntu1, mixed mode, sharing)

2. Downloading Apache Maven

At the time of writing this article, the latest version of Apache Maven is 3.6.3. Before continuing with the next step, visit the Maven download page to see if a newer version is available.

Download the Apache Maven in the /tmp directory:

wget -P /tmp

Once the download is completed, extract the archive in the /opt directory:

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

To have more control over Maven versions and updates, we will create a symbolic link maven that will point to the Maven installation directory:

sudo ln -s /opt/apache-maven-3.6.3 /opt/maven

When a new version is released, you can upgrade your Maven installation, by unpacking the newer version and change the symlink to point to it.

3. Setup environment variables

Next, we’ll need to set up the environment variables. To do so, open your text editor and create a new file named in the /etc/profile.d/ directory.

sudo nano /etc/profile.d/

Paste the following code:

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

Save and close the file. This script will be sourced at shell startup.

Make the script executable with chmod:

sudo chmod +x /etc/profile.d/

Finally, load the environment variables using the source command:

source /etc/profile.d/

4. Verify the installation

To verify that Maven is installed, use the mvn -version command which will print the Maven version:

mvn -version

You should see something like the following:

Maven home: /opt/maven
Java version: 11.0.7, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "5.4.0-26-generic", arch: "amd64", family: "unix"

That’s it. The latest version of Maven is now installed on your Ubuntu system.
