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.

Working with properties


We have now already learned that the Java plugin adds tasks and source sets to our Gradle project; however, we also get a lot of new properties that we can use. Custom properties of a plugin are set in a Convention object of type org.gradle.api.plugins.Convention. A Convention object is used by a plugin to expose properties and methods that we can use in our project. The Convention object of the plugin is added to the convention property of a project. The convention property of a Gradle project is a container for all the Convention objects from the plugins.

We can access the properties from the plugin's Convention object directly as project properties, or we can specify a complete path to the Convention object of the plugin, to get to a property or invoke a method.

For example, the sourceSets property is a property of the Convention object of the Java plugin. With the following task, showConvention, we see the different ways we have to access that property:

task showConvention...
