Gradle is free and open-source build tool used for the Java projects, combining the best features of Ant and Maven. It is flexible and helps developers team to automate and build easier and faster software. In this tutorial we will explain how to install Gradle on Ubuntu 20.04.
Prerequisites
Ensure that you are logged in as root or user with sudo privileges.
Step 1 – Install Java
Gradle requires Java JDK 8 or JRE 8 or higher version on the server to run. To install OpenJDK run the following command:
sudo apt update
sudo apt install openjdk-11-jdk
Verify installed Java version on your system.
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)
Step 2 – Downloading Gradle
After the installing Java on your system, download the latest Gradle distribution release binary file from its official download page. At the time of writing this tutorial, the latest version of Gradle is 6.5.1.
Run the following wget command to download the Gradle binary file:
wget https://services.gradle.org/distributions/gradle-6.5.1-bin.zip -P /tmp
Once the download is complete, extract the zip file in the /opt/gradle directory:
sudo unzip -d /opt/gradle /tmp/gradle-6.5.1-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-6.5.1 /opt/gradle/latest
The Gradle build tool has been configured on your Ubuntu 20.04 system. Later, when upgrading Gradle, unpack the newer version and change the symlink to point to it.
Setup the Environment Variables
Now, we will setup Gradle with PATH environment variable to include the Gradle bin directory. Open your text editor and create a new file with name gradle.sh under the /etc/profile.d directory.
sudo nano /etc/profile.d/gradle.sh
Add the following configuration:
export PATH=/opt/gradle/gradle-6.5/bin:$PATH
Save and close the file.
Make the script executable by running the following chmod command:
sudo chmod +x /etc/profile.d/gradle.sh
Now source the script to apply environment for current shell.
source /etc/profile.d/gradle.sh
At this stage, Grandle is installed on Ubuntu 20.04 Linux system.
Verify Gradle Installation
Run the below command to verify that Gradle is installed properly by checking it’s version:
gradle -v
It should show 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
