How to Install Gradle on Ubuntu 20.04

Gradle is a general-purpose tool used to build, automate, and deliver software. It is primarily used for Java, C++, and Swift projects.

Gradle combines 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 guide explains how to install Gradle on Ubuntu 20.04. We’ll download the latest release of Gradle from their official website.

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 machine.

Enter the following commands to install OpenJDK 11
:

sudo apt updatesudo apt install openjdk-11-jdk

Verify the Java installation by printing the Java version
:

java -version

The output should look something like this:

openjdk version "11.0.7" 2020-04-14
OpenJDK Runtime Environment (build 11.0.7+10-post-Ubuntu-3ubuntu1)
OpenJDK 64-Bit Server VM (build 11.0.7+10-post-Ubuntu-3ubuntu1, mixed mode, sharing)

Downloading Gradle #

At the time of writing this article, the latest version of Gradle is 6.5.1. Before continuing with the next step, check the Gradle releases page
to see if a newer version is available.

Downloading the Gradle binary-only zip file in the /tmp directory using the following wget
command:

VERSION=6.5.1wget https://services.gradle.org/distributions/gradle-${VERSION}-bin.zip -P /tmp

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

sudo unzip -d /opt/gradle /tmp/gradle-${VERSION}-bin.zip

Gradle is regularly updated with security patches and new features. To have more control over versions and updates, we’ll create a symbolic link
named latest, which points to the Gradle installation directory:

sudo ln -s /opt/gradle/gradle-${VERSION} /opt/gradle/latest

Later, when upgrading Gradle, unpack the newer version and change the symlink to point to it.

Setting up the Environment Variables #

We need to add the Gradle bin directory to the system PATH environment variable. 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/latest
export PATH=${GRADLE_HOME}/bin:${PATH}

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

Make the script executable
:

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

Load the environment variables in the current shell session using the source
command:

source /etc/profile.d/gradle.sh

Verifying the Gradle Installation #

To validate that Gradle is installed properly use the gradle -v command which will display the Gradle version:

gradle -v

You should see something like the following:

Welcome to Gradle 6.5.1!

Here are the highlights of this release:
 - Experimental file-system watching
 - Improved version ordering
 - New samples
