Groovy ...

  • 是一个基于Java虚拟机的敏捷动态语言
  • 构建在强大的Java语言之上 并添加了从Python,Ruby和Smalltalk等语言中学到的诸多特征
  • 为Java开发者提供了现代最流行的编程语言特性,而且学习成本很低(几乎为零)。
  • 支持DSL(Domain Specific Languages领域定义语言)和其它简洁的语法,让你的代码变得易于阅读和维护。
  • Goovy拥有处理原生类型,面向对象以及一个Ant DSL,使得创建Shell Scripts变的非常简单。
  • 在开发Web,GUI,数据库或控制台程序时 通过减少框架性代码 大大提高了开发者的效率。
  • 支持单元测试和模拟(对象),可以简化测试
  • 无缝集成 所有已经存在的 Java对象和类库
  • 直接编译成Java字节码,这样可以在任何使用Java的地方 使用Groovy。

Experience the latest Groovy 1.7

Groovy 1.7, 最新的 主要稳定版本 现在被发布了. 要了解更多新特性, 请阅读 release notes. 简要地说, Groovy 1.7 提供了对匿名内部类和嵌套类的支持、 注解(annotations), SQL, Groovy console and Grape 增强, 更强大的断言, 一个 AST 查看器 和 生成器, 完全重写了 GroovyScriptEngine, 等等!

Groovy是一个充满创新理念具有创新精神的项目

JAX 是德国十分重要的Java技术会议(Java conference),每一年该组织都会召开会议评选最具创新精神的项目,评选委员会从40个提名项目中选择十个候选项目,许多优秀项目如Matisse GUI builder(NetBeans的一个插件,用于构建GUI程序)、Nuxeo(企业级内容管理解决方案)等都入围候选,最后Groovy赢得了1等奖!这是一个崇高的荣誉,我们感到非常高兴,特别是和许多非常优秀的项目一起竞赛。另外该奖项的上一期胜出者是Spring framework。

还有,由Dierk König创作出版的畅销书------《Groovy in Action》,也会作为奖品赠予Groovy社团,随后JAX将单独设置Groovy主题的会议进行颁奖。这些奖项证明并肯定了Groovy的创新价值,并说明Groovy在Java社团有不小的影响力

Come and meet the Groovy and Grails developers at the Grails eXchange conference, 该会议专注于Groovy的发展、Grails以及JavaEE和Web2.0。

  Groovy就像Java的一个特别版本,除拥有Java企业级应用的性能及能力之外,也透过像闭包、动态类型、灵活简洁的语法、许多Builder工具等特性使其拥有很Cool的生产力。如果你是一个开发者、测试者或者脚本爱好者,你一定会喜欢Groovy。

Latest news

If you wish to stay up-to-date with our vibrant community, you can learn more about:

And below, you will find the latest announcements:

The Groovy development team is happy to announce the joint releases of the Groovy 2.4.1 and Groovy 2.3.10 of the Groovy programming language for the Java platform.

Both releases are bug fix releases, and while Groovy 2.4.1 is the latest official stable branch, we thought it might be helpful to some projects who are still on the 2.3.x line to get a final release for that branch. But going forward, the 2.3.x branch won’t see any upcoming release.

You can learn more about all the tickets closed by reading:

For reference, you can also read the release notes of Groovy 2.4 if you haven't had a chance to since the announcement.

Head over to the download section of the new Groovy website to download the binary distribution, or update your dependencies accordingly with those new version numbers.

Thanks a lot for all those who contributed to this release!


Groovy 2.4 released

The Groovy team is happy to announce the release of Groovy 2.4.0!

The big highlight of this release is the Android support, which allows developers to write Android applications fully using Groovy, with much less boilerplate code than raw Java.
The team also focused on various improvements in terms of performance, smaller bytecode generation, or memory consumption.
Other interesting aspects worth noticing in this release are:
  • traits can use the @SelfType annotation with static type checking enabled to restrict to what classes traits can be applied
  • GDK methods improvements
  • some refinements to existing AST transformations
  • further Groovysh improvements as well.
Please have a look at the full release notes for Groovy 2.4 to know more about the new features and all the interesting tickets closed.
You can have a look at the 2.4 changelog on the new Groovy website too.
And then, just go grab this release while it's hot!
Thanks a lot to all those who contributed to this release, whether through bug reports, but also with documentation or code contributions through pull requests. All your help is warmly welcome!
Your support of Groovy and its ecosystem is what makes Groovy so strong, and what will allow it to continue making us all more productive for the next decade!
Keep on groovy'ing!
