Gradle Effective Implementation Guide

Overview of this book

Gradle is the next generation in build automation. It uses convention-over-configuration to provide good defaults, but is also flexible enough to be usable in every situation you encounter in daily development. Build logic is described with a powerful DSL and empowers developers to create reusable and maintainable build logic."Gradle Effective Implementation Guide" is a great introduction and reference for using Gradle. The Gradle build language is explained with hands on code and practical applications. You learn how to apply Gradle in your Java, Scala or Groovy projects, integrate with your favorite IDE and how to integrate with well-known continuous integration servers.Start with the foundations and work your way through hands on examples to build your knowledge of Gradle to skyscraper heights. You will quickly learn the basics of Gradle, how to write tasks, work with files and how to use write build scripts using the Groovy DSL. Then as you develop you will be shown how to use Gradle for Java projects. Compile, package, test and deploy your applications with ease. When you've mastered the simple, move on to the sublime and integrate your code with continuous integration servers and IDEs. By the end of the "Gradle Effective Implementation Guide" you will be able to use Gradle in your daily development. Writing tasks, applying plugins and creating build logic will be second nature.

Chapter 10. Writing Custom Tasks and Plugins

In Gradle, we can either write a simple task in a build file where we add actions with a closure, or we can configure an existing task that is included with Gradle. The process of writing our own task is easy. There are different ways in which we can create a custom task, which we will cover in this chapter.

We will see how we can create a new task class in our build file and use it in our project. Next, we will learn how to create custom tasks in a separate source file. We also learn in this chapter how we can make our task reusable in other projects.

We will learn how to write a plugin for Gradle. Similar to writing custom tasks, we will cover the different ways to write a plugin. We will also see how we can publish our plugin and learn how we can use it in a new project.

We can write our tasks and plugins in Groovy, which works very well with the Gradle API, but we can also use other languages, such as Java and Scala. As long as the code is compiled...
