Step 1: Update Your System: Begin by ensuring your Ubuntu system is up to date. In the terminal, execute the following commands:

sudo apt update
sudo apt upgrade

Step 2: Installing OpenJDK: Ubuntu’s default repositories offer convenient access to OpenJDK packages. For this guide, we’ll focus on OpenJDK 11, an LTS version. Install it using the package manager:

sudo apt install openjdk-11-jdk

Step 3: Verify the Installation: Once installation is complete, verify that Java is successfully installed by checking the version:

java -version

The output should display the installed Java version and related details.

Step 4: Set JAVA_HOME (Optional): Setting the JAVA_HOME environment variable is useful for Java development and specific applications. To set it up, find the path to the installed Java version:

sudo update-java-alternatives -l

Next, open the .bashrc file:

nano ~/.bashrc

Add the following line at the end of the file (replace /path/to/java with the path you obtained earlier):

export JAVA_HOME=/path/to/java

Save and exit the editor (Ctrl+X, then Y, then Enter) and apply the changes to the current session:

source ~/.bashrc

Step 5: Installing Latest Apache Maven: Although Ubuntu’s repositories include Maven, it might not be the latest version. To install the latest Maven, download the binary distribution from the Apache Maven website.

  1. Go to the Apache Maven website (https://maven.apache.org/download.cgi) and note the latest version (e.g., 3.8.3).

  2. Use wget to download the binary distribution (replace “3.8.3” with the latest version):

wget https://apache.mirrors.nublue.co.uk/maven/maven-3/3.8.3/binaries/apache-maven-3.8.3-bin.tar.gz
  1. Extract the downloaded archive:
tar -zxvf apache-maven-3.8.3-bin.tar.gz
  1. Move the extracted files to the /opt directory:
sudo mv apache-maven-3.8.3 /opt

Step 6: Set up Environment Variables: To use Maven globally, set up environment variables:

  1. Open the .bashrc file:
nano ~/.bashrc
  1. Add the following lines at the end of the file:
export MAVEN_HOME=/opt/apache-maven-3.8.3
export PATH=$MAVEN_HOME/bin:$PATH

  1. Save and exit the editor (Ctrl+X, then Y, then Enter).

  2. Apply the changes to the current session:

source ~/.bashrc

Step 7: Verify Maven Installation: Check that Maven is installed correctly and is the latest version:

mvn --version

Conclusion: You’ve accomplished the art of setting up OpenJDK and the latest Apache Maven on your Ubuntu machine. With Java and Maven at your disposal, you are now ready to dive into the world of Java development and unleash your creativity in building sophisticated applications and mastering the art of build automation.

Happy coding!
