Maven is a automation tool used to build and manage projects written in C, ruby language, In this blog, I will explain that how to install and configure latest version of Apache Maven on a CentOS 7.

Requirement

CentOS 7 Server
Root privileges

# steps:

Install Java OpenJDK on CentOS 7
Download Apache Maven Binary Files from source file
Configure Apache Maven Environment on centos

First. You need to install the Java on the CentOS 7 server. The apache Maven requires JDK 1.7 or above. So, please install the java software package “java-1.8.0-openjdk-devel “on this server.

# yum install -y java-1.8.0-openjdk-devel
# java -version

If installation is success, you see the following output.

# java -version
openjdk version "1.8.0_201"
OpenJDK Runtime Environment (build 1.8.0_201-b09)
OpenJDK 64-Bit Server VM (build 25.201-b09, mixed mode)

Please download Apache maven from its official website or use following link to download Maven 3.5.4. package to directory /usr/local/src

# cd /usr/local/src
# wget http://www-us.apache.org/dist/maven/maven-3/3.5.4/binaries/apache-maven-3.5.4-bin.tar.gz

After that, extract downloaded file using following command.

# tar -xf apache-maven-3.5.4-bin.tar.gz
# mv apache-maven-3.5.4/ apache-maven/ 

To configure the environments variables to Apache Maven files, you need to create file ‘maven.sh’ in the ‘/etc/profile.d’ directory

# cd /etc/profile.d/
# vim maven.sh

Add the following configuration in maven.sh file

export M2_HOME=/usr/local/src/apache-maven
export PATH=${M2_HOME}/bin:${PATH}

To load the added configuration by using the ‘source’ command.

# chmod +x maven.sh
# source /etc/profile.d/maven.sh

After that, you need to check that Apache Maven installation is successfully or not , run the following maven command.

# mvn -version
