How To Install Gradle on CentOS 7

In this tutorial, we will show you how to install Gradle on CentOS 7. For those of you who didn’t know, Gradle is a free and open-source build automation toolset based on the concepts of Apache Ant and Apache Maven. Gradle provides a platform to support the entire development lifecycle of a software project.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step to step installation of Gradle on CentOS 7 server.

Prerequisites

• A server running one of the following operating systems: CentOS 7.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Gradle on CentOS 7

Step 1. First, let’s start by ensuring your system is up-to-date.

yum clean all
yum -y update

Step 2. Installing OpenJDK.

Gradle requires Java Development Kit (JDK) 7 or higher in order to work. In this tutorial, we will be installing JDK 8. Run the following command to install JDK 8 on your server:

sudo yum install java-1.8.0-openjdk-devel

Verify the Java version by running the following command:

java -version

Step 3. Installing Gradle on CentOS.

Run the commands below to download Gradle, At the time of this writing, the version is 5.1:

wget https://services.gradle.org/distributions/gradle-5.1-bin.zip -P /tmp

Now unzip the downloaded zip file using the following command:

sudo unzip -d /opt/gradle /tmp/gradle-5.1.zip

Step 4. Setup environment variables.

PATH Environment variable should include the Gradle directory. So we should create gradle.sh file inside /etc/profile.d/ directory. To create a file run the following command:

sudo nano /etc/profile.d/gradle.sh

Now paste the following code inside the above file:

export GRADLE_HOME=/opt/gradle/gradle-5.1
export PATH=${GRADLE_HOME}/bin:${PATH}

Then, make the script file executable using the following command:

sudo chmod +x /etc/profile.d/gradle.sh

Load the environment variables using the following command:

source /etc/profile.d/gradle.sh

Step 5. Verify the Gradle installation.

You can run the following command to check if the Gradle install was successful:

gradle -v

You should see the following output:

Welcome to Gradle 5.1!

Here are the highlights of this release:
 - Kotlin DSL 1.0
 - Task timeouts
 - Dependency alignment aka BOM support
 - Interactive `gradle init`
