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.

After finishing download, extract the downloaded package in /opt/gradle directory using zip command

unzip gradle-*.zip

 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
