Methods of Installing Apache Maven on CentOS

Here, you will learn the best methods to install Apache Maven on your system:

• Apache Maven Installation via Yum Package Manager.
• Apache Maven Installation via Direct Download method.

1. Apache Maven Installation via Yum Package Manager

Apache Maven is included in the CentOS default repository. Here, we are going to install Apache Maven on CentOS via the Yum package manager.

So follow the steps given below to do this.

i. Execute the command given below in the Terminal to install Apache Maven on your CentOS system:

$ sudo yum install maven

You might be prompted to enter sudo password, after which the installation of Apache maven will be started.

ii. After the Apache Maven is installed, you can confirm it using this command:

$ mvn --version

This will display the version of Apache Maven installed on the system.

2. Apache Maven Installation via Direct Download method

Apache Maven is also available for download and installation on its official website. Here, we are going to install Apache Maven on the CentOS system. Using this method, you can have the latest release of Maven. Note that we are going to download the current latest version 3.8.1 (as of July 2021). So follow the steps outlined below.

i. Apache maven requires JDK 1.7 or later to be installed on your machine. To verify if Java is installed, run the command below:

$ java --version

If it installed, the output will display the Java version available on the system.

Otherwise, you can install it using the command below in the Terminal:

$ sudo yum install -y java-1.8.0-openjdk-devel

ii. Now, Visit the Apache Maven Downloads page and download the latest or any previous version of Apache Maven. You can also use this command for downloading the Maven 3.8.1:

$ wget https://downloads.apache.org/maven/maven-3/3.8.1/binaries/apache-maven-3.8.1-bin.tar.gz

The downloaded file will be an archive file.

iii. Extract the downloaded Apache Maven archive using the command below:

$ sudo tar xf apache-maven-3.8.1-bin.tar.gz -C /opt

Replace the apache-maven-3.8.1 with your extracted directory name.

This command will extract the archive in a directory named apache-maven-3.8.1 (apache-maven-version_number) in the /opt directory.

iv. Move inside the /opt directory and rename the extracted directory as follows:

$ cd /opt
$ sudo mv apache-maven-3.8.1/ apache-maven

v. Now setup environment variable. To do so, create a file maven.sh in the /etc/profile.d using the command below:

$ sudo nano /etc/profile.d/maven.sh

Now copy-paste the below lines in the maven.sh file:

export M2_HOME=/opt/apache-maven
export MAVEN_HOME=/opt/apache-maven
export PATH=${M2_HOME}/bin:${PATH}

Then save the file and exit the editor.

vi. The maven.sh file created in the previous step is a script file. You will have to make it executable as follows:

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

vii. Apply the configurations as follows:

$ source /etc/profile.d/maven.sh

Now the Apache Maven has been installed. To verify the installation, use the command below:

$ mvn --version

The output will verify the Apache maven version installed in the system.
