Learn how to – Install Apache Maven on CentOS 7 / Fedora 37/36/35/34/33.

Apache Maven is a software project management/automation tool used primarily for managing Java project’s build, reporting, and documentation from a central piece of information. This tutorial will help you to install Apache Maven on CentOS 7 / Fedora 37/36/35/34/33 Linux system.

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

Step 1: Update system & Install Java

Apache Maven requires the host system to have the Java Development Kit. Install OpenJDK on CentOS 7 / Fedora:

Install Java on CentOS 7 / Fedora:

## Java 17 ###
sudo yum -y install wget lsof java-17-openjdk

## Java 11 ###
sudo yum -y install wget lsof java-11-openjdk

After the installation of Java, you can quickly confirm the version using the following command:

$ java -version
openjdk version "17.0.5" 2022-10-18
OpenJDK Runtime Environment (Red_Hat-17.0.5.0.8-1.fc37) (build 17.0.5+8)
OpenJDK 64-Bit Server VM (Red_Hat-17.0.5.0.8-1.fc37) (build 17.0.5+8, mixed mode, sharing)

Step 2: Download and Install Apache Maven

Check  the latest release of Apache Maven and save this to a variable:

export VER="3.8.7"

Download the latest release of Apache Maven exported above:

wget https://downloads.apache.org/maven/maven-3/${VER}/binaries/apache-maven-${VER}-bin.tar.gz

Now extract the downloaded tarball:

tar xvf apache-maven-${VER}-bin.tar.gz

Move the resulting directory to /opt

sudo mv apache-maven-${VER} /opt/maven

Setup Environment Variables to load Apache Maven

cat <<EOF | sudo tee /etc/profile.d/maven.sh
export MAVEN_HOME=/opt/maven
export PATH=$PATH:$MAVEN_HOME/bin
EOF

Source the file

$ source /etc/profile.d/maven.sh
$ echo $MAVEN_HOME
/opt/maven
$ echo $PATH

Your $PATH should have /opt/maven/bin at the end.

Step 3: Verify Apache Maven installation

Finally, validate that Apache Maven has been installed correctly:

$ mvn --version
Apache Maven 3.8.7 (b89d5959fcde851dcb1c8946a785a163f14e1e29)
Maven home: /opt/maven
Java version: 17.0.5, vendor: Red Hat, Inc., runtime: /usr/lib/jvm/java-17-openjdk-17.0.5.0.8-1.fc37.x86_64
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "6.0.11-300.fc37.x86_64", arch: "amd64", family: "unix"

This command should print Maven version and used Java version.

All options are available on:

$ mvn -h

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.

On a successful run, you should get output similar to below:

INFO] ----------------------------------------------------------------------------

The generate goal created a directory with the same name given as the artifactId.

$ 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:

.....
[INFO] ------------------------------------------------------------------------
