How to Install Maven on Debian 12

Apache Maven is an open-source build automation tool primarily used for Java projects. Developed by the Apache Software Foundation, Maven simplifies the process of building, managing, and deploying applications by using a project object model (POM). It automates tasks like compiling code, managing dependencies, running tests, and generating documentation. Running Maven on Debian 12 ensures a stable and efficient development environment, making it ideal for both individual developers and large enterprise teams.

Maven on Debian 12 provides a powerful and efficient platform for building, managing, and deploying Java applications. Its automated build process, dependency management, and multi-module support simplify software development and accelerate project delivery. Whether you’re developing a simple Java application or a complex enterprise system, Maven ensures a consistent, reliable, and scalable development environment.

Step 1: Set Up a Server Instance

To begin, create a Debian 12 server instance by following these steps:

Access Shape.Host Dashboard: Log into your Shape.Host account and navigate to the Dashboard.

Create a New Instance: Click the “Create” button located at the top-right corner.

Select Server Type: Choose “Instances” to configure your server.

Choose a Data Center: Select a location nearest to your audience for better performance.

Select a Hosting Plan: Choose a plan that suits your needs, whether Standard or Memory-Optimized.

Set Up the Operating System: Select Debian 12 as your operating system.

Finalize and Launch: Choose SSH keys or a password for authentication and click Create Instance.

Find your instance’s IP address under the Resources section and use it to access your server.

Step 2: Connect to Your Server

Connect to your server using SSH:

Linux/macOS: ssh root@<your_server_ip>
Windows: Use PuTTY. Enter your server’s IP address, select SSH, and log in using your credentials.

Step 3: Install Required Packages

Step 3.1: Update the System

Ensure your system is up-to-date by running the following command:

apt update

Step 3.2: Install Java Development Kit (JDK)

Maven requires Java to run. Install the default JDK:

apt install default-jdk

Step 3.3: Verify Java Installation

Check the installed Java version to confirm the installation:

java -version

Step 4: Download and Extract Maven

Step 4.1: Download Apache Maven

Download the latest version of Apache Maven:

wget https://dlcdn.apache.org/maven/maven-3/3.9.7/binaries/apache-maven-3.9.7-bin.tar.gz

Step 4.2: Extract Maven to `/opt` Directory

Extract the downloaded archive to the /opt directory:

tar xf apache-maven-3.9.7-bin.tar.gz -C /opt

Step 5: Configure Environment Variables

Step 5.1: Create a Shell Script for Maven

Open the maven.sh script file:

nano /etc/profile.d/maven.sh

Step 5.2: Add Environment Variables

Paste the following lines into the file:

export JAVA_HOME=/usr/lib/jvm/default-java  
export M3_HOME=/opt/apache-maven-3.9.7  
export MAVEN_HOME=/opt/apache-maven-3.9.7  
export PATH=${M3_HOME}/bin:${PATH}

Save the file by pressing Ctrl + X, then Y, and Enter.

Step 5.3: Make the Script Executable

Grant execute permissions to the script:

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

Step 6: Apply Configuration

Step 6.1: Navigate to the Profile Directory

Change to the /etc/profile.d/ directory:

cd /etc/profile.d/

Step 6.2: Verify Script Content

View the contents of maven.sh to ensure the variables are correctly set:

cat maven.sh

Step 6.3: Apply the Configuration Script

Execute the script to apply the environment variables:

bash /etc/profile.d/maven.sh

Step 6.4: Load Environment Variables into Current Session

Use the source command to load the environment variables into the current shell session:

source /etc/profile.d/maven.sh

Step 7: Verify Maven Installation

Confirm that Maven is installed and configured correctly by checking its version:

mvn -version

The output should display the Maven version, Java version, and the environment settings, indicating that Maven is ready for use.

You have successfully installed and configured Apache Maven on Debian 12. With Maven set up, you can now efficiently build, manage, and deploy your Java projects.
