Groovy是一种新兴的 Java 2 平台语言。Groovy 代码能够与 Java 代码很好地结合，也能用于扩展现有代码。目前的 Groovy 版本是 1.6.3，在 Java 1.4 和 Java 5 平台上都能使用，也能在 Java 6 上使用。
Groovy 1.8发行说明如下：
The 1.8 release of Groovy comes with many new features that greatly enhance
·the dynamic expressiveness of Groovy, specifically for defining DSLs
·runtime performance
·concurrent and parallel execution
·">design by contract
·functional programming style
·first-class JSON support
·compile-time meta programming
·and more helpers and library additions
These features have undergone the Groovy developer process with formal descriptions, discussion, and voting (GEP - Groovy Enhancement Proposal) for core parts and less formal developer discussions and JIRA voting for additional parts.
Our goal has stayed the same, though: to give the Java developer a tool that makes him more productive, allows him to achieve his goals faster and with a smaller margin of error, and extend the scalability of the Java platform from full-blown enterprise projects to everyday "getting things done" tasks.
