Welcome to the learning section of the Groovy website.
First of all, you will need to get started by installing Groovy on your system or project.
Once all set up, we invite you to have a look at the Groovy documentation, which explains all the details of the language, such as how to use the tools that come with a Groovy installation, and how to tackle more complex tasks with the various module user guides.
But there are other ways to learn more about Groovy, thanks to books and presentations given about Groovy at conferences.
Books
Another great approach to learning Groovy is to read the various books published on the language:
Presentations
Many Groovy-related presentations have been recorded at conferences that you might wish to have a look at, to learn more about Groovy, delve into particular topics, and more.
Below are a few selected presentations given at Groovy-related conferences.

Groovy is a well established player in the JVM since a few years ago. Its increased popularity across the years has spawned several projects that conform the Groovy Ecosystem. You've probably heard of Grails, Gradle, Griffon and Spock. But what about the rest of projects that are just waiting around the corner to be discovered and make your life easier? This talk presents them tools and libraries that use Groovy as the main driving force to get the job done.

The dynamic runtime nature of Groovy is one of the things that sets it apart from standard Java and makes it a fantastic language for building dynamic applications for the Java Platform. The metaprogramming capabilities offered by the language provide everything that an application development team needs to build systems that are far more capable than their all Java counterparts. This Part 1 of 2 will cover the runtime metaprogramming capabilities of Groovy. The session will dive deep into Groovy's Meta Object Protocol (MOP) which implements the incredibly dynamic runtime dispatch mechanism. The session will include a lot of live code demonstrating really powerful runtime features of the language. This session is focused specifically on Groovy's runtime metaprogramming capabilities. Part 2 of 2 will cover Groovy's compile time metaprogramming capabilities

Remember the epic Java Puzzlers? Here's the Groovy version, and we have some neat ones! Even though we are totally a Grails shop here at JFrog, some of these had us scratching our heads for days trying to figure them out. And there is more! Contributions from the truly Groovy senseis, including Guillaume Laforge, Andrés Almiray, Tim Yates, Ken Kousen make this talk an unforgettable journey to Groovy. In this talk, you'll have the expected dose of fun and enlightenment hearing about our mistakes and failures, great and small, in hard core Groovy/Grails development.

Courses
Another great resource for learning Groovy is through a course. You could spend time hunting down various videos on the web but these courses have all the information you need packed into one place.

I am going to teach you everything you need to know to start using The Groovy Programming language. If you're a beginner programmer with a some experience in another language like Python or Ruby this course is for you. Dynamic languages are generally thought of as easier for total beginners to learn because they're flexible and fun. If you're an existing Java Developer (Beginner or Experienced) this course is also for you.
This course is packed with almost 14 hours of content. We are going to start off with getting your development environment up and running and then go through the very basics of the language. From there we are going to build on that in each section cover topics like closures, meta-programming, builders and so much more.

Learn the advantages of using Groovy by itself and with existing Java projects. This video workshop takes you into the heart of this JVM language and shows you how Groovy can help increase your productivity through dynamic language features similar to those of Python, Ruby, and Smalltalk.
By Ken Kousen
Take your basic Groovy skills to the next level with this practical video workshop. Presenter and Java consultant Ken Kousen shows you how to work with XML and JSON, implement runtime metaprogramming, and use several AST transformations. You'll also dive into operator overloading, Groovy SQL, and the Groovy JDK.
By Ken Kousen
Learn advanced techniques for working with the Groovy programming language. In this video workshop, presenter and Java consultant Ken Kousen shows you how to create RESTful web services, conduct Unit Tests, apply Groovy's functional programming features, and use Java's Spring Framework in conjunction with Groovy.
By Object Computing
This 2-day, comprehensive course covers a lot of material and takes JVM developers from beginner to advanced with the Groovy language by way of comprehensive lecture, demonstration, and hands-on exercises. Developers will leave the experience with all of the skills needed to effectively use the Groovy programming language to build many kinds of JVM applications.
By Object Computing
The course covers, in-depth, how Groovy's dynamic dispatch mechanism works and how application and plugin code can participate with that dispatch mechanism to provide more simple application code. You'll also learn techniques that may be applied at compile time to enhance classes, including AST Transformations, automatically enhancing Grails artifacts with traits and more.
