By: Hubert Klein Ikkink

Overview of this book

Gradle is a project automation tool that has a wide range of applications. The basic aim of Gradle is to automate a wide variety of tasks performed by software developers, including compiling computer source code to binary code, packaging binary codes, running tests, deploying applications to production systems, and creating documentation. The book will start with the fundamentals of Gradle and introduce you to the tools that will be used in further chapters. You will learn to create and work with Gradle scripts and then see how to use Gradle to build your Java Projects. While building Java application, you will find out about other important topics such as dependency management, publishing artifacts, and integrating the application with other JVM languages such as Scala and Groovy. By the end of this book, you will be able to use Gradle in your daily development. Writing tasks, applying plugins, and creating build logic will be your second nature.

Defining tasks

A project has one or more tasks to execute some actions, so a task is made up of actions. These actions are executed when the task is executed. Gradle supports several ways to add actions to our tasks. In this section, we discuss about the different ways to add actions to a task.

We can use the doFirst and doLast methods to add actions to our task, and we can use the left-shift operator (<<) as a synonym for the doLast method. With the doLast method or the left-shift operator (<<), we add actions at the end of the list of actions for the task. With the doFirst method, we can add actions to the beginning of the list of actions. The following script shows how we can use the several methods:

task first { 
    doFirst { 
        println 'Running first' 
task second { 
    doLast { Task task -> 
        println "Running ${}" 
// Here we use the << operator 
// as synonym for the doLast method. 
task third << { taskObject...
