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.

Chapter 2. Building Java Projects

In the previous chapter, we saw a very basic build script, which just printed the customary Hello World on the console. Now that we are comfortable with the Gradle command line interface, it's a perfect time for us to jump-start our journey with a simple Java project.

In this chapter, we will see how to build and test simple Java projects with Gradle, how external dependencies are added to the classpath, and how building distributable binaries work.

We will try to keep the Java code as minimal as possible so that we can focus more on the build of the project. Along the way, we will learn some best practices that a Gradle-based project should follow. It's okay if we are not able to comprehend all the build script syntax in this chapter because we are going to see that in detail in Chapter 4, Demystifying Build Scripts.
