How to install Apache Maven on Ubuntu 22.04
Apache Maven is a software project management/automation tool used primarily to manage Java project builds, reporting, and documentation from one central piece of information. This guide will help you install Apache Maven on Ubuntu 22.04
Maven exists to help you simplify and standardize all of your project build processes. Maven will handle authoring, distribution, documentation, team collaboration, and other project tasks seamlessly. It also increases reusability and takes care of most of the tasks involved.
Maven data structure:
Item | Default |
---|---|
Source code | ${basedir}/src/main/java |
Resources | ${basedir}/src/main/resource |
Check | ${basedir}/src/test |
Bytecode compliance | ${basedir}/target |
Distributable JAR | ${basedir}/target/class |
Update the system and install Java
Apache Maven requires the server system to have the Java Development Kit. Install OpenJDK on Ubuntu/Debian.
apt update
apt install -y default-jdk tree
Check your installed Java version using:
$ java -version
Download and install Apache Maven
Check out the latest release of Apache Maven and save it to a variable:
export VER="3.9.6"
Download the latest release of Apache Maven exported above:
wget https://downloads.apache.org/maven/maven-3/3.9.6/binaries/apache-maven-3.9.6-bin.tar.gz
Now extract the downloaded tarball:
tar xvf apache-maven-3.9.6-bin.tar.gz
Move the resulting folder to /opt
mv apache-maven-3.9.6 /opt/maven
Set up environment variables to load Apache Maven
cat <<EOF | tee /etc/profile.d/maven.sh
export MAVEN_HOME=/opt/maven
export PATH=\$PATH:\$MAVEN_HOME/bin
EOF
File source
$ source /etc/profile.d/maven.sh
$ echo $MAVEN_HOME
/opt/maven
$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/opt/maven/bin
You $PATH
should be /opt/maven/bin
at the end.
Verify installation
Finally, validate that Apache Maven has been installed correctly:
$ mvn --version
This command will print the Maven version and Java version used.
All options are available on:
mvn -h
Create a Maven project 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, executing may take some time. Maven downloads the most recent artifacts (plugin jars and other files) to your local repository.
When run successfully, you will get results similar to those below:
Created generate goal
a folder with the same name as ArtifactId.
$ tree my-app/
- The directory
src/main/java
contains the project source code - The directory
src/test/java
contains the test source - This file
pom.xml
is the project’s Project Object Model (POM).
This file pom.xml
is the core of the project configuration in Maven. It contains most of the information needed to build a project.
Project construction
To build your Project, run:
root@Greencloud:~/mvn-projects# ls my-app root@Greencloud:~/mvn-projects# cd my-app/ root@Greencloud:~/mvn-projects/my-app# ls pom.xml src root@Greencloud:~/mvn-projects/my-app# mvn package
The command line will print out various actions and end with the following information:
