Gradle Effective Implementations Guide - Second Edition

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.

Preface

Organizing tasks


In Chapter 1Starting with Gradle, we already discussed that we could use the tasks task of Gradle to see the tasks that are available for a build. Let's suppose we have the following simple build script:

defaultTasks 'second' 
 
task first << { 
    println "I am first" 
} 
 
task second(dependsOn: first) << { 
    println "I am second" 
} 

Nothing fancy here. The second task is the default task and depends on the first task. When we run the tasks task on the command line, we get the following output:

$ gradle -q tasks
------------------------------------------------------------
All tasks runnable from root project
------------------------------------------------------------
Default tasks: second
