The following Gradle tutorial covers the basics of the framework. Topics covered include Introducing Gradle, Projects and Tasks, and Managing dependencies. The course also includes a video and other resources. The tutorial is part of the DZone Learning Center. It links related articles, online learning communities, and a community mailing list.
Introducing Gradle
Introducing Gradle is a quick-start primer that helps you learn the basics of the build and release process. It also covers the Gradle life cycle and the Gradle build tool. Afterwards, you’ll understand how Gradle can be leveraged in your development process. Using Gradle will help you create high-quality software in a shorter time.
The build process involves several steps: compiling, unit testing, packaging, and running the application. This process is complex and requires some understanding of terminology. However, once you know the basic steps, you can use Gradle to create your custom-built applications. In this book, you’ll learn how to leverage the various tools Gradle provides to automate your development process.
Gradle is a build tool for Java developers. It can create projects on multiple platforms based on a series of build tasks. It can run serially or in parallel and is extensible for new features. It is available separately or as a part of Android Studio.
Tasks in Gradle
Gradle supports two types of tasks. One type is a simple task, where the task is defined as a function with an action closure. This type of task is helpful for one-off tasks. The other type, called a lifecycle task, does not change any outputs. Either way, the task will be triggered whenever Gradle executes the project.
Tasks in Gradle can also be grouped by name. By default, Gradle will deliver functions assigned to the default group. However, you can add jobs to groups by typing Gradle-tasks into the command prompt. You can also skip lessons in Gradle. The only() method is attached to the study to cut a job. The only() way only executes a commission if the predicate is factual. Passing a closure that returns correctly if the task is performed and false if skipped.
Projects in Gradle
Gradle builds your application as a series of files. Each file is called a Gradle project. Each Gradle project has its name, and the Gradle build script gives this name. Gradle projects represent your application and library. You can change the name of your project by searching for it in your project folder.
In the Gradle Tool Window, you can see all your dependencies. Asterisks indicate that a dependency is missing. You can also click on an asterisk to see all its locations. Understanding the structure of your project is essential for a successful Gradle to build. It’s also important to understand the build scripts and tasks. To use Gradle, click on the Gradle tab in Android Studio. Then, repeat the task name to execute it. The result will be a long string. If you want to abbreviate the task, you can use camel-case notation.
Managing dependencies in Gradle
Managing dependencies is the core concept behind the Gradle build system. When a project has multiple external modules, Gradle needs to know where to find them. This location is called a repository. A repository can be either a local directory or a remote one. Gradle offers several different types of repositories.
Gradle adds dependencies to the classpath during the build process. Dependencies can also be exported to other modules. This allows you to make these dependencies available at compile and runtime. In addition, you can use this configuration to add a dependency to your project only when you need it. This is especially useful for Android modules that need dependencies during compilation. Using this configuration requires the library module to check whether or not the reliance is available and change its behaviour if not. The advantage of using this configuration is that it reduces the size of the app. However, it is essential to remember that this configuration cannot be used for AAR dependencies.
Gradle has several features that make it easy to manage dependencies. For example, it provides a dependency graph you can visualize and navigate. This helps you identify when version conflicts exist and can help you resolve them. Gradle also has a dependency tool that you can use to analyze the dependency graph.
Using a Gradle plugin
To use a Gradle plugin, you must first install it in your Eclipse IDE. You can do this by visiting the Gradle plugin portal. The plugin portal also includes instructions on how to publish your plugin. Once you have installed it, you can use it in your projects.
A Gradle plugin packages reusable build logic. This means you can reuse and share one project’s sense with others. You can create a plugin in any language that you want. For example, a plugin can be written in bytecode or scripting.
Most Gradle builds use plugins to accomplish different tasks. Plugins are simple and reusable. This article was updated to use Gradle 7.2, Spock 3, and JUnit 5. Plugins can automatically configure your Gradle task graph and various build elements.
