Groovy 通过以下方式落实了这些宗旨：

使开发人员不用编译。

允许动态类型。

使合成结构容易。

使其脚本可以在普通 Java 应用程序中使用。

提供一个 shell 解析器。

The main purpose of the above quote is apparently to stun the user into a stupor by firing alot buzz words at you, and to avoid telling you what Groovy is at all costs. What it probably should say is, were I the publicist for the team, would be:

The Spille Version Groovy is a new scripting language built on top of the standard Java 1.4 JVM. It combines features from languages like Python, Ruby, Smalltalk, and Perl in a very Java-like syntax which has full interoperability with Java classes and code. The language looks like a close cousin to Java, but implements decidedly non-Java constructs such as Closures, regular expressions, here-documents, and optional relaxation of static typing as first class language constructs.

You might say that Groovy feels an awful lot like Ruby, but looks far more like Java - and most importantly Groovy code can directly call Java code, and vice versa, and Groovy itself compiles down to plain old Java bytecodes.
