How to Install Gradle on Debian 10

Gradle is a powerful and flexible build tool used primarily for Java projects, combining the best features of Ant and Maven . Unlike its predecessors, which use XML for scripting, Gradle uses Groovy , a dynamic, object-oriented programming language for the Java platform to define the project and build scripts.

This article describes how to install Gradle on Debian 10 Linux.

Prerequisites

The instructions assume that you are logged in as root or user with sudo privileges .

Installing OpenJDK

Gradle requires Java SE 8 or later to be installed on the server.

Execute the following command to install the OpenJDK package:

sudo apt updatesudo apt install default-jdk

Verify the Java installation by running:

java -version

The output should look something like this:

openjdk version "11.0.6" 2020-01-14
OpenJDK Runtime Environment (build 11.0.6+10-post-Debian-1deb10u1)
OpenJDK 64-Bit Server VM (build 11.0.6+10-post-Debian-1deb10u1, mixed mode, sharing)

Downloading Gradle

At the time of writing this article, the latest version of Gradle is 6.3. Before continuing with the next step, you should check the Gradle releases page to see if a newer version is available.

Run the following wget command to download the Gradle binary file:

wget https://services.gradle.org/distributions/gradle-6.3-bin.zip -P /tmp

Once the download is completed, extract the zip file in the /opt/gradle directory:

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

Verify that the Gradle files are extracted:

ls /opt/gradle/gradle-*
bin  init.d  lib  LICENSE  NOTICE  README

Setting up the Environment Variables

Next, we’ll need to configure the PATH environment variable to include the Gradle bin directory. To do so, open your text editor and create a new file named gradle.sh inside of the /etc/profile.d directory.

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

Paste the following configuration:

/etc/profile.d/gradle.sh
export GRADLE_HOME=/opt/gradle/gradle-6.3
export PATH=${GRADLE_HOME}/bin:${PATH}

Save and close the file. This script will be sourced at shell startup.

Make the script executable by running the following chmod command:

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

Load the environment variables using the source command:

source /etc/profile.d/gradle.sh

Verifying the Gradle Installation

To validate that Gradle is installed properly run the following command which will display the Gradle version:

gradle -v

You should see something like the following:

Welcome to Gradle 6.3!

Here are the highlights of this release:
 - Java 14 support
 - Improved error messages for unexpected failures
