Apache Groovy v2.4.7 發布

Groovy 是一種動態語言。它和 Java 一樣，也運行于 Java 虛擬機中。你可以認為 Groovy 擴展了 Java 語言。Groovy 對自己的定義就是：Groovy 是在 java 平臺上的、 具有像 Python， Ruby 和 Smalltalk 語言特性的靈活動態語言， Groovy 保證了這些特性像 Java 語法一樣被 Java 開發者使用。除了語言和 Java 相通外，Groovy 有時候又像一種腳本語言。執行 Groovy 腳本時，Groovy 會先將其編譯成 Java 類字節碼，然后通過 Jvm 來執行這個 Java 類。Groovy的主要特點：

• 使JAVA程序員以幾乎為0的學習曲線獲得現代的編程特性
• 為你的代碼提供靜態檢查和靜態編譯能力以提供健壯性和高性能
• 提供領域特定語言（Domain-Specific Languages）和其他緊湊的語法使你的代碼變得容易閱讀和維護
• 使用強大的處理原生類型，面向對象和Ant DSL使編寫shell和腳本變得容易
• 在開發Web，GUI，數據庫或控制臺程序時通過減少框架的代碼提高開發人員的生產力
• 通過提供的單元測試和模擬開箱即用（out-of-the-box）來簡化測試
• 與所有現有的Java類和庫無縫集成
• 直接編譯成JAVA字節碼，所以你可以用在任何你用JAVA的地方
