What is Gradle?
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 project configuration. Groovy is a dynamic, object-oriented programming language to define the project configurations. Follow the below steps to cover the Installation of Gradle on Ubuntu 18.04 / 16.04 / Linux Mint 19 & Debian
Requirements:

Move the downloaded package to working directory
sabi@sabi:~$ mv gradle-6.0.1-bin.zip /tmp/
After finishing download, extract the downloaded package in /opt/gradle directory using zip command
unzip gradle-*.zip
Create a directory called /opt/gradle
sudo mkdir /opt/gradle
Copy the extracted files to the /opt/gradle
sudo cp -pr gradle-*/* /opt/gradle
You can confirm the extracted files by listing them in /opt/gradle directory.
sabi@sabi:/tmp$ cd /opt/gradle
sabi@sabi:/opt/gradle$ ls
bin getting-started.html init.d lib LICENSE NOTICE
Step 3: Setting Up Environment Variables
Configure the path environment variable to include the Gradle’s bin directory. For this create a new file inside the /etc/profile.d/ directory.
sudo nano /etc/profile.d/gradle.sh
Paste the below data into the above file and save it.
export PATH=$PATH:/opt/gradle/gradle-6.0.1/bin
Type the given command to make the script executable.
sudo chmod +x /etc/profile.d/gradle.sh
Now, load the environment variables for the current session by
source /etc/profile.d/gradle.sh
Step 4: Verifying the Installation
Check the version of Gradle using gradle -v command
gradle -v
Output:
sabi@sabi:/tmp$ gradle -v
