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.

Project dependencies


In real life, we work on a lot more complex applications than what we have just seen. Such applications rely on other specialized components to provide some functionality. For example, an Enterprise Java application's build may depend on various components such as open source libraries in Maven central, libraries developed and hosted in-house, and (maybe) even on another subprojects. Such dependencies are, themselves, located at various locations like, local intranet, local filesystem, and so on. They need to be resolved, downloaded, and brought into the appropriate configuration (such as compile, testCompile, and so on) of the build.

Gradle does an excellent job in locating and making dependencies available in the appropriate classpath and packaging if required. Let's begin with the most common kind of dependencies—external libraries.

External libraries

Almost all real-world projects depend on external libraries for reusing the proven and tested components. Such dependencies...
