Monday I’ll be flying to San Francisco for the JavaOne conference, where there will be tons of sessions and BOF speaking about Groovy or mentioning it, and where I’ll be participating at two sessions, one of the novelties of Groovy 2 and the ScriptBowl. Let me highlight a few of those sessions: What’s new in Groovy 2 Shameless plug, that’s my session, where I speak about some of the key features of Groovy 1. Read more...

The Groovy development team’s just released Groovy 2.0.4, a bug fix for our Groovy 2.0 branch. It fixes some important issues we’ve had with generics with the stub generator, as well as several fixes related to the static type checking and static compilation features. We also worked on the recompilation issues with the GroovyScriptEngine. You can download Groovy 2.0.4 here: http://groovy.codehaus.org/Download The artifacts are not yet on Maven Central, but will shortly. Read more...

I’ll echo here the two new releases of the Groovy programming language: This is with great pleasure that the Groovy development team announces the releases of Groovy 2.0.2 and Groovy 1.8.8. Those two releases are essentially just bug fix releases, with only minor improvements. In particular, work has been done in the area of the static type checker and static compilation, in the GroovyScriptEngine, as well as further performance improvements for the “invoke dynamic” support as well as plain Groovy.

The Groovy development team is happy to announce the releases of Groovy 2.0.1, 1.8.7 and 1.7.11! That’s the first time we release three versions at the same time. Those three versions are essentially just bug fix releases. The 1.8.7 release contains a lot of the bugfixes that were already integrated in Groovy 2.0.0, so it’s just an alignment with the Groovy 2 branch. In the future, Groovy 1.8.x and Groovy 2.

Although I’ve gone at length through the key major features of Groovy 2.0in the InfoQ article, there have been a few smaller ones which are interesting to note. And groovy guys like Tim Yates, André Steingress or Mr Hakki were quick to blog about them! inject() method with a default initial value takeWhile() and dropWhile() methods withDefault(), withEager() methods matchesPartially() method for matchers (to see if a string might match a pattern given more input) @NotYetImplemented transformation for test cases an iterable collectEntries() variant first() and last() working with iterables as well collate() method (although it’s also in 1.

There are various options for building your Groovy projects: including Ant with the Groovyc Ant task, or with Gradle Groovy plugin. But today, I’d like to speak about Maven. You have actually two possible choices: GMaven or the Groovy Eclipse Maven plugin. GMaven GMaven 1.4 already allowed you to use Groovy 2.0 even before the final release of Groovy, although a new 1.5 version is about to be released soon, which should also include the option to use the “invoke dynamic” support which is currently missing for GMaven 1.

Right after the release of Groovy 2.0, our intrepid Eclipse team released a new version of the Groovy Eclipse plugin. The big highlights are, of course, the Groovy 2.0 support, but also the support of Juno and the move of the sources of the plugin to GitHub, plus some new refactorings and quickfixes. Here’s Andrew’s full announcement: Hot on the heels of Groovy 2.0, we are pleased to announce the release of Groovy-Eclipse 2. Read more...

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. In this article, we’re going to look into those new features in more detail. A “static theme” for a dynamic language Static type checking Groovy, by nature, is and will always be a dynamic language.

The Groovy development team is very pleased to announce the release of Groovy 2.0, the highly popular dynamic language for the Java platform. For the key highlights of this important milestone, Groovy 2.0 comes packed with: a static type checker to let the compiler tell you about the correctness of your code, static compilation for the performance of the critical parts of your application, modularity, splitting the Groovy JAR into smaller feature-oriented JARs and letting you create your own extension modules, JDK 7 Project Coin syntax enhancements, so that Groovy is still as friendly as possible with its Java cousin, and JDK 7 Invoke Dynamic integration to benefit from the support of the JVM for dynamic languages.

Along with the release of Gaelyk 1.2, I’d like to share two interesting links about running functional tests with Geb, and concurrency / parallelism with GPars on Gaelyk. Gaelyk functional testing with Geb In the Groovy ecosystem, we’re all aware of the Spock testing framework. On top of Spock, you can use the Geb browser automation library, to easily create functional tests for your web applications, in a nice, readable and expressive fashion. Read more...
