For more details on whats included in this release please see the release notes:

AribaWeb 5.0, the component-based UI web UI framework for creating RIA/AJAX apps without writing JavaScript, is newly available as Open Source (Apache License). AribaWeb provide the Groovy developer with:

  • Auto AJAX: full AJAX UI from server-side Groovy code

Most of the examples are written in Groovy (Java is also supported) as can be seen in these screencasts.

Gmock 0.6.0 released

We are pleased to announce the release of Gmock 0.6.0. Gmock is a mocking framework for the Groovy language. Gmock is all about simple syntax and readability of your tests so you can spend less time learning the framework and more writing code.

This release add:

  • the support for static property mocking
  • introduction of a with(mock) syntax
  • setting up expectation using the mock closure
  • adding a static closure as a syntax shortcut

Please visit or for more information.

We are looking for your feedback and how you feel we could improve Gmock in the route to the 1.0.0.

This is with very great pleasure and honor that I'm announcing the final release of Groovy 1.6, on behalf of the Groovy development team and SpringSource.
Obviously, 1.6 is a very important milestone for the project, with several great new features and improvements:

  • great runtime performance improvements
  • multiple assignments- optional return in if/else and try/catch blocks
  • AST transformations and all the provided transformation annotations like @Singleton, @Lazy, @Immutable, @Delegate and friends
  • the Grape module and dependency system and its @Grab transformation
  • various Swing builder improvements, thanks to the Swing / Griffon ( team
  • as well as several Swing console improvements
  • the integration of JMX builder
  • JSR-223 scripting engine built-in
  • various metaprogramming improvements, like the EMC DSL, per-instance metaclasses even for POJOs, and runtime mixins

An article will be published in the coming days on InfoQ and GroovyMag coming back on all those features and novelties with more details.

You can download Groovy 1.6 at the usual place:
Additional installers and bundles will be provided soon.

And you can also have a look at the JIRA changelog listing features, improvements and bug fixes.

Very big thanks to all the developers who contributed to the project, in particular our most prolific ones like Paul, Roshan, Danno and Jochen, and to all our users who've helped shape the project, thanks to their great feedback and suggestions.

Let me also mention an interesting event which is shaping up: the GR8 Conference, a conference dedicated to Groovy, Grails and Griffon, organized by the Danish JUG and SpringSource!
