Overview

In this intensive and highly practical 2-day Gradle course, you will become familiar with all major concepts of Gradle and how to best use Gradle for simple as well as complex build scenarios. This course is packed with hands-on exercises. You will learn about the basic language elements of the Gradle Domain Specific Language (DSL), how to use Gradle's build-by-convention for plain Java and Java web projects, and how to use the Gradle plugin system. You will find out how easy it is to customize your build. You will learn about Gradle's mighty dependency management. And much more ...

Course Prerequisites

This course assumes a good understanding of the Java language. Some code is initially easier to understand if you also have a basic understanding of the Groovy language. But due to Groovy's similarity to Java, Groovy is not a prerequisite. There will be a very short introduction to Groovy at the beginning of the course.
