Gradle In-Depth

Learn everything you need to know about Gradle in three days.


The Gradle In-Depth training course is an extensive hands-on three day Gradle training course for build masters and developers who are authoring their builds. Participants will learn how to use the Gradle build system to substantially increase their productivity. This Gradle training class first runs through some Groovy fundamentals and then moves quickly into thorough in-depth coverage of the Gradle build system.

Participants will spend a significant portion of the class with their hands on the keyboard, learning by doing, working through lab exercises designed to build on the presented material and explore the depths of Gradle. This class can take you from complete newcomer status to Gradle competence. Due to the in-depth treatment of the topics it is also very suitable for people who have experience working with Gradle. The class will be delivered by a Gradle Core Developer which gives you access to the deepest Gradle knowledge available. No question will remain unanswered.


3 days


Once the training is complete participants will:

  • Learn the basics of Gradle and Groovy
  • Learn how Gradle integrates with Android
  • Write your own Gradle plugins
  • Integrate with Ant and Maven
  • Learn about copy and archive tasks in Gradle
  • Work with a powerful file system API
  • Build migration best practices
  • Learn how to use the Gradle performance
  • Learn how to build Java applications
  • How to efficiently move away from your current build environment
  • Learn how to deal with complex build requirements
  • Learn how to deal with large multi module builds


New and experienced users are encouraged to attend Gradle In-depth. This class has something for every level of Gradle user.


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.
