Groovy is a new agile dynamic language for the JVM combining lots of great features from languages like Python, Ruby and Smalltalk and making them available to the Java developers using a Java-like syntax.

Groovy is designed to help you get things done on the Java platform in a quicker, more concise and fun way - bringing the power of Python and Ruby inside the Java platform.

Groovy can be used as an alternative compiler to javac to generate standard Java bytecode to be used by any Java project or it can be used dynamically as an alternative language such as for scripting Java objects, templating or writing unit test cases.

Features

Closure support
Native syntax for Lists and Maps
Groovy Markup
Groovy Path expression language
Groovlets for implementing Servlets easily in simple Groovy scripts
Groovy SQL for making SQL more Groovy
Groovy Beans for simpler syntax for working with beans
Groovy Template Engines which are pluggable, simple to use, integrate GPath and compile to bytecode
Ant Scripting
Regex syntax for neater scripting with regular expressions
Operator Overloading to simplify working with datatypes Collections and Maps
Polymorphic iteration and Autoboxing
Compiles straight to Java bytecode & works cleanly with all existing Java objects & libraries

Groovy 2.0.8 and 2.1.3 released

Heads up on a joint bug-fix release, with Groovy 2.0.8 and 2.1.3.

We released the 2.0.8 bug fix in particular for Grails which was affected by a couple issues but that hadn't planned on migrating just yet to the 2.1.x line.

If you want to learn more about the issues closed, please have a look at the JIRA release notes for Groovy 2.0.8 and Groovy 2.1.3.

Head down to the Download section to download our the latest releases.

Thanks for all your contributions, and keep on groovy'ing!

Getting started

Probably the best way to get started on Groovy is to install a binary distribution and play with it.

Or try reading the user guide or browsing some of the links on the left of this page.

Current build status

The Groovy project uses DamageControl as a Continuous Integration system to make Groovy build automatically. The little coloured bubble on the left show the status of the last automatic build: if it's green, the build was successful, if it's red, the build failed. And if it is pulsating, it means there's a new build currently in the works.
