Groovy Goodness: Create Dynamic Methods
In Groovy we can write classes and write an implementation for methods we don't even know exist. We must implement the method methodMissing() which is invoked when other methods cannot be found. Because methodMissing() is invoked each time another method cannot be found, it can be expensive, but we can use the metaClass property to cache the new method. Next time the cached version is used. class
Groovy Goodness: Invoke Methods Dynamically
In Groovy we can invoke a method just like in Java: we simply type the name of the method in our code. But what if we want to invoke a method name, but we don't know the name yet when we write the code, but we do know it at runtime? We can use the Reflection API for example to invoke the method, but in Groovy it can be shorter. In Groovy we can use a variable value for method invocation with a GSt
Groovy Goodness: Add Methods Dynamically to Classes with ExpandoMetaClass
We can add new behaviour, like methods, to classes in Groovy dynamically. So this means a method is not added to the class definition in the source code, but to the class definition while an application is already running. Groovy adds a metaClass property to all classes for this purpose. The type of this property is ExpandoMetaClass. We can assign methods (also static), properties, constructors to

Groovy - ConfigSlurper
ConfigSlurper is a utility class within Groovy for writing properties file like scripts for performing configuration. Unlike regular Java properties files ConfigSlurper scripts support native Java types and are structured like a tree. Below is an example of how you could configure Log4j with a ConfigSlurper script: log4j.appender.stdout = "org.apache.log4j.ConsoleAppender" log4j.appender."stdout.l
Groovy - Unit Testing
The Groovy Advantage Groovy simplifies JUnit testing, making it more Groovy, in several ways, including: JUnit is built into the groovy runtime, so you can script JUnit tests for your Groovy and Java classes using Groovy syntax. Groovy provides many additional JUnit assertion statements (see below) Groovy unit tests are easily scriptable with Ant / Maven (see below) Groovy provides Groovy Mocks Se

Groovyベースのビルド管理ツールGradleを使ってみる - 豆無日記
Gradleってなに？ 簡単に言えばMaven2のようなものですね。 あらかじめ様々な機能がプラグインとして用意されているビルドツールです。 勝手に選んだ主な特徴のトップ3は↓。 設定ファイルをXMLではなく、GroovyによるDSLで書く(build.gradleファイル) Groovyコードを含むプロジェクトの設定が非常に簡単 Maven2のディレクトリ構成を踏襲しているので、Maven2との同居も可能 といった感じで、とりあえずあっさりと流しておきます 入手・インストールなど ↓ダウンロードはこちらからどうぞ。 http://www.gradle.org/ 展開したディレクトリをGRADLE_HOME環境変数に指定して、PATHに$GRADLE_HOME/bin通すだけの、よくあるインストール方法です。 $ gradle --version ---------------------
