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.

Preface

Testing our projects


Gradle has a built-in support for running tests for our Java projects. When we add the Java plugin to our project, we will get new tasks to compile and run tests. We will also get the testCompile and testRuntime dependency configurations. We use these dependencies to set the class path for running the tests in our code base:

  1. Let's write a simple JUnit test for a sample Java class. The implementation of gradle.sample.Sample has the getWelcomeMessage() method, where we read a text from the file property and then return the value. The following example contains the code for the Sample class:

            // File: src/main/java/gradle/sample/Sample.java 
            package gradle.sample; 
     
            import java.util.ResourceBundle; 
     
            /** 
            * Read welcome message from external properties file 
            * <code>messages.properties</code>. 
            */ 
    
  2. Next, we must add the resource property file that is used by the Sample class. We will create the messages...
