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.

Building Groovy projects


Let's first implement the QotdService interface in Groovy. Also, we will write some unit tests to make sure that the functionality works as expected. To start the project, let's create the directory structure as follows:

qotd-groovy
├── build.gradle
└── src
    ├── main
    │   ├── groovy
    │   │   └── com
    │   │       └── packtpub
    │   │           └── ge
    │   │               └── qotd
    │   │                   └── GroovyQotdService.groovy
    │   └── java
    │       └── com
    │           └── packtpub
    │               └── ge
    │                   └── qotd
    │                       └── QotdService.java
    └── test
        └── groovy
            └── com
                └── packtpub
                    └── ge
                        └── qotd
                            └── GroovyQotdServiceTest.groovy

The src/main/java directory is the default directory for Java sources. Similarly, src/main/groovy is used by default to compile Groovy source files...
