Different ways on installing Apache Maven on Rocky Linux

You can install Apache Maven via different methods such as through the DNF / YUM package manager or install from the source binary package which gives you the latest version. 

1. Apache Maven Installation via DNF / YUM package manager

To install Apache Maven using DNF, run the command:

Note that this method will not always give you the latest release of Maven.

To confirm the version of Apache version installed, execute the command:

$ mvn --version

2. Apache Maven Installation via the source binary package

Using this method, you can Install the latest version of Apache Maven. To do this, follow the steps given below.

i. Update the system

First, update the packages on your system:

$ sudo dnf update

ii. Install OpenJDK

Maven 3.3 and later versions require OpenJDK 1.7 and recent versions to install. We will install the latest LTS release which, at the moment, is OpenJDK 11. To achieve this, run the command:

$ sudo dnf install java-11-openjdk-devel

To confirm the version of OpenJDK installed, run:

$ java -version

iii. Download Apache Maven archive

The next step is to download Apache Maven. The latest version, at the time of writing this guide, is Apache Maven 3.8.2. By the time you are reading this guide, chances are that another version will be the latest release. So, check Apache Maven's download page.

Next, extract the archive to the /opt directory:

$ sudo tar -xvf apache-maven-3.8.2-bin.tar.gz -C /opt

Thereafter, create a symbolic link that points to the installation directory:

$ sudo ln -s /opt/apache-maven-3.8.2 /opt/maven
