Gradle Effective Implementation Guide

Overview of this book

Gradle is the next generation in build automation. It uses convention-over-configuration to provide good defaults, but is also flexible enough to be usable in every situation you encounter in daily development. Build logic is described with a powerful DSL and empowers developers to create reusable and maintainable build logic."Gradle Effective Implementation Guide" is a great introduction and reference for using Gradle. The Gradle build language is explained with hands on code and practical applications. You learn how to apply Gradle in your Java, Scala or Groovy projects, integrate with your favorite IDE and how to integrate with well-known continuous integration servers.Start with the foundations and work your way through hands on examples to build your knowledge of Gradle to skyscraper heights. You will quickly learn the basics of Gradle, how to write tasks, work with files and how to use write build scripts using the Groovy DSL. Then as you develop you will be shown how to use Gradle for Java projects. Compile, package, test and deploy your applications with ease. When you've mastered the simple, move on to the sublime and integrate your code with continuous integration servers and IDEs. By the end of the "Gradle Effective Implementation Guide" you will be able to use Gradle in your daily development. Writing tasks, applying plugins and creating build logic will be second nature.

Using the PMD plugin


Another tool for analyzing the Java source code is PMD. It finds unused variables, empty catch blocks, unnecessary object creation, and so forth. We can configure our own rule sets and even define our own rules. To use PMD with Gradle, we have to apply the PMD plugin to our build. After we have added the plugin, we have the pmdMain and pmdTest tasks already installed. These tasks will run PMD rules for the main and test source sets. If we have a custom source set, then the plugin adds a pmd<SourceSet> task as well. These tasks are also dependency tasks of the check task. So if we invoke the check task, all the pmd tasks are executed as well.

This plugin only defines a structure to work with PMD, but doesn't contain the actual PMD library dependencies. Gradle will download the PMD dependencies the first time that we invoke the pmd tasks. We have to define a repository that contains the PMD libraries, such as the Maven Central repository or a corporate intranet repository...
