How to install Gradle on Ubuntu 20.04?

Hi, folks. In this post dedicated to Java, you will learn how to install Gradle on Ubuntu 20.04

Gradle is an open-source build automation tool used for Java, Groovy, and Scala development. Basically, it builds upon the concepts of Apache Ant & Apache Maven. Gradle uses Groovy instead of XML for declaring the project configuration. Groovy is a dynamic, object-oriented programming language to define the project configurations.

So, let us start.

Installing Gradle on Ubuntu 20.04

Gradle is important for the effective development of Java applications. So the first requirement is to install Java on Ubuntu 20.04.

At the time of writing this post, the latest stable version of Gradle is 6.5.1 So, check first which is the latest version and modify the command.

If you don’t have the unzip command installed, do it because we will need it.

sudo apt install unzip

Now unzip the downloaded file into a directory like /opt/ where it will remain indefinitely:

:~$ sudo unzip -d /opt/gradle gradle-6.5.1-bin.zip

The next step is to make Gradle available from anywhere in the terminal. Also, make it available to all users.

To do this, create a new file called gradle.sh in /etc/profile.d/

:~$ sudo nano /etc/profile.d/gradle.sh

And add the following content:

export GRADLE_HOME=/opt/gradle/gradle-6.5.1
export PATH=${GRADLE_HOME}/bin:${PATH}
3.- Configuring Gradle
3.- Configuring Gradle

Save the changes, and close the editor.

Assign execution permissions to the file:

:~$ sudo chmod +x /etc/profile.d/gradle.sh

And finally, source the file to apply the changes:

:~$ source /etc/profile.d/gradle.sh

Now you can use Gradle from the terminal. So, check the installation, showing the version of the program:

:~$ gradle -v
