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.

We used a println method in our Gradle build scripts to see some output, but we can also use Gradle's logging mechanisms to have a more customizable way to define logging messages.

Gradle supports several logging levels that we can use for our own messages. The level of our messages is important as we can use the command-line options to filter the messages for log levels.

The following table shows the log levels that are supported by Gradle:

Every Gradle build file and task has a logger object. The logger object is an instance of a Gradle-specific...
