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.

The application will be based on Servlet 3.1 specification. We will reuse the GreetService that we developed in the previous chapter. The form will be served by a static HTML file, which can post data to our servlet. The servlet will create a greeting message and forward it to a JSP for rendering.

Creating source files

Let's create the root of the project as hello-web. The structure is similar to what we had seen for a simple Java application, with one addition, which is the web app root. The Web app root, by default, is located...
