Install Gradle on Debian

Gradle is a free and opensource general purpose build tool used mainly for Java projects. It uses Groovy which is dynamic, object-oriented programming language to define projects and build scripts for Java language. Gradle is also used for building Android projects in Android Studio. In this tutorial, you are going to learn how to install Gradle on Debian 9.

Prerequisites

Before you start to install Gradle on Debian. You must have the non-root user account on your server/desktop with sudo privileges.

Install OpenJDK

First update apt package manager index in Debian typing following command:

sudo apt update

sudo apt install openjdk-8-jdk

Confirm the OpenJDK installation typing following command:

java -version

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

Setup Environment Variables

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

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

Now paste following code inside above file.

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

Save the file and close the file.

Now make script file executable using following command:

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

Load the environment variables using following command:

source /etc/profile.d/gradle.sh

gradle -v
