Preface Welcome to Gradle Beyond the Basics, the second book in the O’Reilly Gradle series. This book picks up from its predecessor, Building and Testing with Gradle, and takes you further into the Gradle programming model. We offer the recipes, techniques, and syntax that make Gradle more than just free-form scripting, and place your build instead on the foundation of a strong domain model. The difference is, it is your domain model, not a generic one from some build tool that is ignorant of the specifics of your project. Having introduced you to the basic elements of Gradle in the first book, we can begin to explore the tool’s capabilities a bit more deeply. We will cover four discrete areas of Gradle functionality: file operations, custom Gradle plug-ins, build lifecycle hooks, and dependency management. We assume that you are familiar with the basics of how to use Gradle, and with a keen respect of your time and interest, offer no further intro‐ duction to the mechanics of simple Gradle builds. If you are brand new to the topic, you should definitely read Building and Testing first. The Gradle APIs are rich, the possibilities for DSLs matching your domain are abundant, and the path towards finally having a build system that conforms to your product is clear. Let’s move forward.
