Learn how to – How to install Apache Maven on RHEL / CentOS 8.

This tutorial serves as a step by step guide on how to install Apache Maven on RHEL / CentOS 8. Apache Maven is a software project management and automation tool used for managing the Java project’s build, reporting, and documentation from a central piece of information.

For CentOS 7 / Fedora: Installing Latest Apache Maven on CentOS 7 / Fedora

For Debian / Ubuntu use: Install Latest Apache Maven on Ubuntu / Debian

The Apache Maven package is available on RHEL 8 upstream repositories. Run the command below as a user with sudo privileges.

sudo yum -y install @maven

Java will be installed as a dependency. Wait for the installation to finish then check the version of Apache Maven installed on your RHEL 8 system.

$ mvn --version
Apache Maven 3.5.4 (Red Hat 3.5.4-5)
Maven home: /usr/share/maven
Java version: 1.8.0_181, vendor: Oracle Corporation, runtime: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181.b13-9.el8.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.18.0-32.el8.x86_64", arch: "amd64", family: "unix"

All options are available on:

$ mvn -h

Testing Apache Maven on RHEL / CentOS 8

Create Maven projects directory:

mkdir ~/mvn-projects && cd ~/mvn-projects

Create your first project:

mvn archetype:generate -DgroupId=com.mycompany.app 
 -DartifactId=my-app 
 -DarchetypeArtifactId=maven-archetype-quickstart 
 -DinteractiveMode=false

Since this is the first run,  it may take a while to execute.  This is because Maven is downloading the most recent artifacts (plugin jars and other files) into your local repository.

$ tree my-app/
 my-app/
 ├── pom.xml
 └── src
     ├── main
     │   └── java
     │       └── com
     │           └── mycompany
     │               └── app
     │                   └── App.java
     └── test
         └── java
             └── com
                 └── mycompany
                     └── app
                         └── AppTest.java
 11 directories, 3 files

• The src/main/java directory contains the project source code
• The src/test/java directory contains the test source
• The file pom.xml is the project’s Project Object Model (POM).

The filepom.xml is the core of a project’s configuration in Maven. It contains the majority of information required to build a project.

Build the Project

To build your Project, run:

mvn package

The command line will print out various actions, and end with the following:

...
