About the Technology

In the last ten years, Groovy has become an integral part of a Java developer’s toolbox. Its comfortable, common-sense design, seamless integration with Java, and rich ecosystem that includes the Grails web framework, the Gradle build system, and Spock testing platform have created a large Groovy community

About the Book

Groovy in Action, Second Edition is the undisputed definitive reference on the Groovy language. Written by core members of the Groovy language team, this book presents Groovy like no other can—from the inside out. With relevant examples, careful explanations of Groovy’s key concepts and features, and insightful coverage of how to use Groovy in-production tasks, including building new applications, integration with existing code, and DSL development, this is the only book you’ll need. Updated for Groovy 2.4.

Some experience with Java or another programming language is helpful. No Groovy experience is assumed.
