Apache Maven is an open-source Java tool for the standardized creation and management of Java-based projects. As per the developers of Maven, it is intended to facilitate the daily development work by trying to automate as many steps as possible in the development cycle from the creation of a software project to compilation and testing to the distribution of the software.

sudo apt update
2. Install Apache Maven on Ubuntu 22.04
Well, we can install Maven using the default system repository of Ubuntu 22.04 and other versions of Ubuntu. However, you will not have the latest version of it instead well tested and stable one.

wget https://dlcdn.apache.org/maven/maven-3/3.8.5/binaries/apache-maven-3.8.5-bin.tar.gz
Extract the file:
tar -xvf apache-maven-*-bin.tar.gz
Check the extracted file name:
ls
Move it to /usr/share/
sudo mv apache-maven-3.8.5 /usr/share/maven
