The newly released Groovy 2.0 brings key static features to the language with static type checking and static compilation, adopts JDK 7 related improvements with Project Coin syntax enhancements and the support of the new "invoke dynamic" JVM instruction, and becomes more modular than before.

The big change in this release candidate is the modularity aspect. We've now fully switched to Gradle, as our build tool, to build a more modular Groovy. You still have a big "all" JAR, but if you're interested in just picking the core JAR and the needed modules for your project, you can now do so. The following modules, also available as Maven artifacts, have been created and extracted: ant, bsf, console, docgenerator, groovydoc, groovysh, jms, json, jsr-223, servlet, sql, swing, templates, test, testng, xml.
Also, it's possible for you to create your own extension modules, which will provide additional methods to JDK or third-party classes, just like Groovy does with the Groovy Development Kit. For more information on this extension module system, please have a look at this page explaining the details. We're looking forward to your feedback on this release! Download.

But what's going on, weren't we working on the 1.9 line?

Groovy. Customize Groovy Console Visual Output.
The Groovy Console ($ groovyConsole) is a great tool to run Groovy scripts and experiment with Groovy.
Normally when we run a script the return result (if not null) is shown as a string value. We can customize the way the value is shown by creating a new file with the name OutputTransforms.groovy in our GROOVY_HOME directory. Normally this directory is located in your user directory with the name .groovy. In OutputTransforms.groovy we must fill the internal script variable transforms of type ArrayList with a closure where we do the actual customization of the return result. The closure has one parameter which is the return result of the script. Groovy 1.8.3 and 1.9-beta-4 released. Those two releases are essentially about bug fixes and minor enhancements, but we also have interesting developments going on for static type checking your Groovy code, and for invoke dynamic support for performance of our dynamic core.
But it'll be better that I save those topics for some future posts! Here, I just wanted to highlight some of the minor enhancements in those two new releases. Such enhancements sometimes go unnoticed, so I thought it would be nice to put them a bit more in the spotligh. Customize your groovysh prompt A pretty old request was about the ability to customize your groovysh prompt, so that instead of "groovy", you could have your own message. If you want to customize your groovysh prompt, there are two approaches: either you export an environement variable called GROOVYSH_PROMPT, or you pass the -Dgroovysh.prompt=myMessage argument to your groovysh launch command.

O’Reilly is celebrating the release of Java 7, and our inaugural OSCON Java conference: July 25-27 in Portland, Ore. The possibility of using alternative languages on the JVM has always been an appealing side story to Java. Jython and JRuby were early pioneers in implementing a dynamic language on top of a statically typed VM. Now that Java 7 directly includes support in the JVM for dynamic languages, the coexistence is official. Pick any of the languages here and you can expect the support of the robust JVM threading and garbage collection, plus access to a broad array of application libraries. Ten Groovy One Liners to Impress Your Friends. Language Comparison: Compute Factorial - Groovy, Java, and ColdFusion.
We Recommend These Resources A friend of mine is in school and taking some classes in Java, and also happens to be learning ColdFusion on the side. He was talking about the class and how they were learning about recursion and how they used the example of computing the factorial of a given number. Just for fun I took that opportunity to do this in a couple of languages... just to see what they look like side by side.
Please note there are no advantages or disadvantages to any of these code samples, but instead is shown as something educational... food for the brain if you will. :) **ColdFusion** Day 1. For the first time this year Gr8Conf organized a university day. On this day 3 hour sessions where given about Groovy (in the morning) and Grails (in the afternoon). In the morning I did the session about Getting Groovy together with Søren Berg Glasius (one of the organizers of Gr8Conf). We had a lot of topics to cover and didn't make it to cover it all during the session. Luckily we created a big document with all the topics and a lot of sample code (also from the Groovy Goodness blog series) for the attendees.
So hopefully people will look into the document to learn more about the topics we couldn't cover. Interviews: Peter Gromov on IntelliJ's Groovy support. Hello and welcome to another DZone interview. Without a doubt IntelliJ IDEA is the IDE of choice of many Groovy developers out there, simply because it was the first IDE to raise the bar in terms of support for the language -- and continues to do so. Peter Gromov is currently in charge of all things Groovy on IntelliJ, let's hear what he has to say about his experiences with the language. Enjoy!

The following Groovy script provides a brute force mechanism for searching the online JDK 7 Javadoc API documentation for methods, classes, enums, methods, and interfaces that contain the string "1.7.
" I threw this together quickly and believe there are several more elegant ways to do this, but this was easy to write and does the job. The above Groovy script searches the Javadoc documentation for "1.7" and provides a list of Javadoc files for classes, enums, interfaces, and methods that include the "1.7" string. According to the script's output, 4020 files were searched and 304 of those files contained at least once occurrence of the "1.7" string. The following Javadoc HTML files were identified by the script as containing the string "1.7" somewhere within the page's documentation. Release Notes - groovy - Version 1.7.10 - HTML format.
