h3 Introduction to Groovy

Groovy is a new agile dynamic language for the JVM combining lots of great features from languages like Python, Ruby and Smalltalk
and making them available to the Java developers using a Java-like syntax.

Groovy is designed to help you get things done on the Java platform in a quicker, more concise and fun way - bringing the power
of Python and Ruby inside the Java platform.

Groovy can be used as an alternative compiler to javac to generate standard Java bytecode to be used by any Java project
or it can be used dynamically as an alternative language such as for scripting Java objects, templating or writing unit test cases.

h3 Getting started

Probably the best way to get started on Groovy is to

and
play with it.

Or try reading the

h3 News

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!


Groovy 2.4 released

The Groovy team is happy to announce the release of Groovy 2.4.0!

The big highlight of this release is the Android support, which allows developers to write Android applications fully using Groovy, with much less boilerplate code than raw Java.
The team also focused on various improvements in terms of performance, smaller bytecode generation, or memory consumption.
Other interesting aspects worth noticing in this release are:
  • 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.
Please have a look at the full release notes for Groovy 2.4 to know more about the new features and all the interesting tickets closed.
You can have a look at the 2.4 changelog on the new Groovy website too.
And then, just go grab this release while it's hot!
Thanks a lot to all those who contributed to this release, whether through bug reports, but also with documentation or code contributions through pull requests. All your help is warmly welcome!
Your support of Groovy and its ecosystem is what makes Groovy so strong, and what will allow it to continue making us all more productive for the next decade!
Keep on groovy'ing!
