Gradle is a powerful build automation tool, primarily used for Java, Groovy, and Kotlin, that embraces the domain-specific language approach rather than XML form for project configuration. Coursera's Gradle skills catalogue teaches you the fundamentals of build script definitions within Gradle, its plugin architecture, and its customization capabilities. You'll learn how to manage project dependencies, perform testing, and generate reports, as well as how to create single and multi-project builds. Through this, you'll gain a better understanding of how to automate your development process, improve productivity, and ensure software quality using Gradle.
