Gradle Effective Implementations Guide - Second Edition

By: Hubert Klein Ikkink

Overview of this book

Gradle is a project automation tool that has a wide range of applications. The basic aim of Gradle is to automate a wide variety of tasks performed by software developers, including compiling computer source code to binary code, packaging binary codes, running tests, deploying applications to production systems, and creating documentation. The book will start with the fundamentals of Gradle and introduce you to the tools that will be used in further chapters. You will learn to create and work with Gradle scripts and then see how to use Gradle to build your Java Projects. While building Java application, you will find out about other important topics such as dependency management, publishing artifacts, and integrating the application with other JVM languages such as Scala and Groovy. By the end of this book, you will be able to use Gradle in your daily development. Writing tasks, applying plugins, and creating build logic will be your second nature.

Using the Scala plugin

We can also use Gradle to work with Scala source files. We can have a Scala-only project or both Java and Scala source files in our project. We must apply the Scala plugin to enable the Scala support for our build. The plugin adds new tasks to compile the Scala source files. With the compileScala task, we compile our main Scala source files. The source files must be in the src/main/scala directory. The compileTestScala task compiles all Scala source code files that are in the src/test/scala directory. The plugin also adds a compile<SourceSet>Scala task for custom-defined source sets in our build.

The compile tasks support both Java and Scala source files with joint compilation. We can place our Java source files in say the  src/main/java directory of our project and the Scala source files in the src/main/scala directory. The compiler will compile both types of files. To be able to compile the files, we must add dependencies to the Scala library in our build file...
