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 2.1.5 bug fix release

Dear all,

I'm pleased to announce the release of Groovy 2.1.5.

Groovy 2.1.5 is a bug fix release of the Groovy 2.1 branch. In particular, it fixes a problem we've encountered with Groovy 2.1.4 where the extension module descriptors were not found in the "all" JAR, which meant that the usual nice GDK methods extensions for XML and other modules were not found by Groovy.

You can download Groovy 2.1.5 in the download area and have a look at the JIRA release notes.

Thanks to all who contributed to this release!

Keep on groovy'ing!
