Overview of this book

Gradle is an advanced and modern build automation tool. It inherits the best elements of the past generation of build tools, but it also differs and innovates to bring terseness, elegance, simplicity, and the flexibility to build. Right from installing Gradle and writing your first build file to creating a fully-fledged multi-module project build, this book will guide you through its topics in a step-by-step fashion. You will get your hands dirty with a simple Java project built with Gradle and go on to build web applications that are run with Jetty or Tomcat. We take a unique approach towards explaining the DSL using the Gradle API, which makes the DSL more accessible and intuitive. All in all, this book is a concise guide to help you decipher the Gradle build files, covering the essential topics that are most useful in real-world projects. With every chapter, you will learn a new topic and be able to readily implement your build files.

So far, we have seen how to create a standalone custom plugin and include it in another project build file. Gradle also allows you to configure plugin properties and customize them as per your project's need. You have already learned how you can customize the source code location and test code location in a java plugin. We will see an example of how you can replicate the same behavior in your custom plugin. To define plugin properties, you need to create one additional extension class and register the class into your plugin class. Let's say we want to add the location property to the plugin. Create the CustomPluginExtension.groovy class as follows:

package ch8
class CustomPluginExtension {
def location = "/plugin/defaultlocation"
}

Now, register this class to your plugin class:

class CustomPlugin implements Plugin<Project> {
  void apply(Project project) {
    def extension = project.extensions.create("customExt",CustomPluginExtension)

project.task('task1') <&lt...
