Gradle is an open source automation application used for building, testing, publishing, deployment for generating static websites, documentations, etc.. The latest version of Gradle is released with a lot of changes. Not only is Gradle a easy-to-use tool, its installation is also easy.We have already covered the Installation of Gradle on Debian in our previous article, and its installation on Ubuntu is covered in this article.

Before you start the installation of Gradle, make sure you have Java installed on your Ubuntu machine. You can check your version of Java by running the following command.

user1@linuxhelpubnt:~$ java -version
java version " 1.8.0_121" 
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

 Gradle is a Groovy based build system.

Gradle is build automation evolved. Gradle can automate the building, testing, publishing, deployment and more of software packages or other types of projects such as generated static websites, generated documentation or indeed anything else.

Gradle combines the power and flexibility of Ant with the dependency management and conventions of Maven into a more effective way to build. Powered by a Groovy DSL and packed with innovation, Gradle provides a declarative way to describe all kinds of builds through sensible defaults. Gradle is quickly becoming the build system of choice for many open source projects, leading edge enterprises and legacy automation challenges.
