Groovy ...
- is an agile dynamic language for the Java Platform
- builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk
- makes modern programming features available to Java developers with almost-zero learning curve
- supports Domain Specific Languages and other compact syntax abbreviations so you can easily write concise meaningful maintainable code
- makes writing shell scripts and build scripts easy with its powerful processing primitives, a touch of OO programming and an Ant DSL
- increases developer productivity by reducing scaffolding code when developing web, GUI, database or console applications
- greatly simplifies testing by supporting unit testing and mocking out-of-the-box
- cleanly integrates with all existing Java objects and libraries and compiles straight to Java bytecode
Groovy, a creative and innovative project
JAX is the most important Java conference in Germany. Every year, the organizers are running a contest to select the most innovative and creative projects. From over 40 proposals, the jury selected only ten nominees. Although great projects were selected, like the Matisse GUI builder in NetBeans, or the Nuxeo Enterprise Content Management solution, Groovy won the first prize! It is a great honor and a huge pleasure for us to receive such a prize, especially knowing the cool projects we were competing with, or the past winners like the Spring framework.
Dierk König, author of the best-selling "Groovy in Action" book, received the prize in the name of the Groovy community, after having presented several sessions on Groovy at this conference. This award proves and reaffirms how innovative, creative and influential the Groovy project is for the Java community.
Come and meet the Groovy and Grails developers at the Grails eXchange conference, featuring dedicated tracks on Groovy, Grails, Java EE and Web 2.0.

"Groovy is like a super version of Java. It can leverage Java's enterprise capabilities but also has cool productivity features like closures, builders and dynamic typing. If you are a developer, tester or script guru, you have to love Groovy."

Dear all,
I'm pleased to announce the release of Groovy 2.1.5.
Groovy 2.1.5 is a bug fix release of the Groovy 2.1 branch. In particular, it fixes a problem we've encountered with Groovy 2.1.4 where the extension module descriptors were not found in the "all" JAR, which meant that the usual nice GDK methods extensions for XML and other modules were not found by Groovy.
You can download Groovy 2.1.5 in the download area and have a look at the JIRA release notes.
Thanks to all who contributed to this release!
Keep on groovy'ing!
