Download and Configure Maven on Ubuntu 22.04

Steps to Download and Configure Maven on Ubuntu Server Running Jenkins

Pre-requisites:

Before installing Maven on your Ubuntu server where Jenkins is running, ensure that Java is already installed. If not, you need to install Java first. Follow the steps below:

Installing Java on Ubuntu

1. Update package lists:

    sudo apt-get update
   

2. Install OpenJDK 17:

    sudo apt install -y --no-install-recommends openjdk-17-jdk-headless
   

3. Verify Java installation:

    java -version
   

Download and Install Maven

1. Download Maven: Visit the official Maven site here to obtain the latest Maven release.

2. Copy Binary Tarball Link: Copy the link for the binary tar.gz archive from the Maven website.

3. Navigate to Opt Directory: Switch to the /opt directory using the terminal:

    sudo su -
    cd /opt
   

4. Download Maven Archive: Use wget to download the Maven binary tar.gz archive:

    wget <paste_binary_tarball_link_here>
    wget https://dlcdn.apache.org/maven/maven-3/3.9.6/binaries/apache-maven-3.9.6-bin.tar.gz
   

5. Extract Archive: Extract the downloaded tarball:

    tar -xvzf apache-maven-<version_number>-bin.tar.gz
    tar -xvzf apache-maven-3.9.6-bin.tar.gz
   

6. Rename Directory: Rename the extracted directory for convenience:

    mv apache-maven-<version_number> maven
    mv apache-maven-3.9.6 maven
   

7. Set Environment Variables: Open .bash_profile in a text editor:

    sudo vi ~/.bash_profile
   

   Add the following lines to set Java and Maven environment variables:

    export JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64
    export M2_HOME=/opt/maven
    export M2=/opt/maven/bin
    export PATH=$PATH:$M2_HOME:$M2:$JAVA_HOME
   

   Save and exit the editor.

8. Reload Profile: Apply the changes to the current session:

    source ~/.bash_profile
   

Configure Jenkins

1. Install Maven Integration Plugin: Navigate to Jenkins dashboard -> Manage Jenkins -> Manage Plugins -> Available. Search for "Maven Integration" plugin, install, and restart Jenkins.

2. Configure Maven and Java Paths: Navigate to Jenkins dashboard -> Manage Jenkins -> Global Tool Configuration. Add JDK and Maven installations, specifying the paths set earlier.

Build Maven Project in Jenkins

1. Create Maven Project: In Jenkins, create a new item and select "Maven Project".

2. Project Configuration:

   • Provide a name and description for the project.

   • Choose the Git repository for your project.

     

   • Select "Build Root POM" and specify the path to pom.xml in your repository.

3. Build Configuration:

   • In the build configuration, define the Maven goals and options such as clean package or clean install.

     

4. Save and Build: Save the configuration and trigger a build to test the setup.
