Start building powerful apps that take advantage of the dynamic scripting capabilities of the Groovy language, including what´s new in Groovy version 3.0. This book covers Groovy fundamentals, such as installing Groovy, using Groovy tools, and working with the Groovy Development Kit (GDK). You´ll also learn more advanced aspects of Groovy, such as using Groovy design patterns, writing DSLs in Groovy, and taking advantage of Groovy´s functional programming features.

Also, Learning Groovy 3 has been updated to Groovy 3.0 to include the new Parrot parser which was extended to support additional syntax options and language features. It also includes coverage of Groovydoc, which allows you to embed Groovydoc comments in various ways. And, this book covers how Groovy supports Java type annotations and more.

There is more to Groovy than the core language, so Learning Groovy 3, Second Edition covers the extended Groovy ecosystem. You´ll see how to harness Gradle (Groovy´s build system), Grails (Groovy´s web application framework), Spock (Groovy´s testing framework), and Ratpack (Groovy´s reactive web library).
