Groovy is ...
An agile dynamic language for the Java Platform with many features that are inspired by languages like Python, Ruby and Smalltalk, making them available to Java developers using a Java-like syntax.
Developing web applications , writing shell scripts easily, writing concise, meaningful, test cases using Groovy's JUnit integration, or prototyping and producing real industrial strength applications have never been so concise and groovy.
Groovy works cleanly with all existing Java objects and libraries and compiles straight to Java bytecode in either application development or scripting mode.
Groovy provides powerful additional :
- language conceptual enhancements
- Support for closures - re-usable blocks of code
- Native syntax for lists and maps
- Support the Gof Builder pattern via the notion of builders
- Syntax level regex operators and escape sequences
- Native JavaBean support
- Operator overloading to simplify working with datatypes Collections and Maps
- Polymorphic iteration and autoboxing
- Extension of Java Standard Library through the GDK
- useful standard features to enhance developer productivity such as:
- Groovy Markup for XML, DOM, ...
- Groovy Path expression language
- Groovlets for implementing Servlets easily in simple Groovy scripts
- Ant Scripting
- Groovy Categories allow you to add methods to classes with the "use" keyword
- Groovy Template Engines which are pluggable, simple to use, integrate GPath and compile to bytecode
- Gant : a build tool for scripting Ant tasks using Groovy scripts, no XML.
- Grails : Groovy-based web framework inspired by Ruby on Rails
- Gram : a simple xdoclet-like tool for processing doclet tags or Java 5 annotations
- COM Scripting
- GroovySWT : wrapper around SWT , the eclipse graphical library
- Error rendering macro 'link' : Link needs a name and a URL as arguments.: accessing through groovy web services
- GSP : Groovy server pages
- GSQL : accessing databases through Groovy
- Process : handling external processes
- XML-RPC : RPC over HTTP really easily
- Jabber-RPC: RPC over Jabber based instant messaging systems (including Google Talk)
- Error rendering macro 'link' : Link needs a name and a URL as arguments.: Use the Google Data APIs easily from within Groovy
- GORM : Grails Object-Relational Mapping
- Groovy Monkey: Eclipse Monkey port to Groovy with some enhancements.
Enjoy making your code groovier !!!!
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!
The Groovy team is happy to announce the release of Groovy 2.4.0!
- 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.
