How To Install Gradle On Ubuntu

Source – linuxhelp.com

Gradle is a free and open source automation toolset based on Apache Ant and Apache Maven and builds support for development lifecycle. It uses domain specific language rather than XML form for project configuration. This tutorial explains the installation procedure of Gradle on Ubuntu.

Installation procedure

To start the installation procedure, first update the system repositories using the apt-get update command.

root@linuxhelp1:~# apt-get update

After installing Java check its version by running the following command.

root@linuxhelp1:~# java -version
openjdk version "1.8.0_121"

OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)

Next download the package for gradle using the below command.

root@linuxhelp1:~# wget https://services.gradle.org/distributions/gradle-3.4.1-bin.zip

Now to install gradle inside /opt/ directory, create a directory for gradle inside /opt/ by running the following command.

root@linuxhelp1:~# mkdir /opt/gradle

Extract the package directly into /opt/gradle/ directory.

root@linuxhelp1:~# unzip -d /opt/gradle gradle-3.4.1-bin.zip
