The Windows-Installer for Groovy 1.5.1 can now be downloaded from the Groovy Website (direct link). It takes care of the gory details of a Windows installation, copying files, setting environment variables and file associations.

The installer contains the Groovy 1.5.1 Binaries, API Docs and a PDF snapshot of the Wiki, the native launcher, Gant 1.0.2, Scriptom 1.5, version 0.4.2 of GraphicsBuilder, SwingXBuilder 0.1.5 and JideBuilder 1.0. The installation of everything but the binaries is optional.

Currently supported languages for the installer are english, german, spanish, french and brazilian portuguese.

The Groovy development team and G2One are pleased to announce the release of Groovy 1.5.1 -- a bug fix release for Groovy 1.5 as a Christmas present.

It fixes a few problems that were discovered after the release of Groovy 1.5.0. In particular: a dead lock in the Groovy classloader, and a problem with input streams with the Ant builder. Also, a problem in highly concurrent setups on multi-processor machines made Groovy run anormally slowly, and this new release also fixes this problem and makes Groovy run much faster using the full power of all the CPUs.

If you haven't read it already, you can discover all the novelties in Groovy 1.5 by reading Guillaume Laforge's article on InfoQ.

An article written by Guillaume Laforge has just been published on InfoQ, detailing the new features and improvements provided by Groovy 1.5. If you want to know more about the Java 5 additions (annotations, generics, enums), the new meta-programming capabilities, the improved and new tooling support, or the novelties in the Swing builder, you should not miss it.

InfoQ: What's new in Groovy 1.5? 

Groovy 1.5 released

G2One, Inc., the Groovy & Grails professional services company, and the Groovy development team are proud to announce the release of Groovy 1.5.

Groovy is a dynamic language for the JVM that integrates seamlessly with the Java platform. It offers a Java-like syntax, with language features inspired by Smalltalk, Python or Ruby, and lets your reuse all your Java libraries and protect the investment you made in Java skills, tools or application servers. Groovy can be used for various purposes, from adhoc shell scripting leveraging Java APIs, to full-blown web applications built on Spring and Hibernate through the Grails web framework. It can also be integrated very easily in your applications to externalize business logic, create Domain-Specific Languages, or to provide templating, XML parsing capabilities, and much more.

This major release integrates features offered by Java 5: annotations, generics, static imports and enums, making Groovy the sole alternative dynamic language for the JVM that lets you leverage frameworks that use annotations like Spring's @Transactional or JBoss SEAM which both provide extended Groovy support, or generics to help JPA or Hibernate properly handle typed collections.

In this release, new meta-programming capabilities have been contributed thanks to the work of the Grails project developers, pursueing our symbiotic relationship. A few syntax enhancements have also found their way into it to help ease the development of Domain-Specific Languages. Groovy's Swing builder support, to help you build Swing UIs, has almost completely been rewritten and spiced up with several useful additions. For more details on this, Danno Ferrin listed what has changed in SwingBuilder.. A great attention to performance improvements made this new version much snappier than before, as witnessed by a reports we had by teams working on mission-critical applications using Groovy as a business language.

Since Groovy 1.0, the team also worked on improving the tool chain by creating a joint Java / Groovy compiler to let you mix and match Groovy and Java classes in the same compilation step. A GroovyDoc equivalent to JavaDoc lets you document your Groovy classes. The rewritten interactive shell is now really interactive and provides useful command completions for making you more productive, and the Groovy Swing console has also been improved thanks to our talented Swing team and the help of Swing expert Romain Guy.

Initially, the Groovy team expected to call the release 1.1, as shown by the various betas and release candidates for 1.1, but considering the breadth of improvements and new features, the team decided to rebrand it to 1.5, which corresponds more to the level of maturity and quality of the language, following the path of other projects such as Spring jumping from 2.1 to 2.5 right before the release. 

Apart from improvements or the creation of these new tools, you should have a look at JetBrains' JetGroovy, a fantastic Groovy and Grails plugin which provides advanced coding capabilities to IntelliJ IDEA:

Of course, if you're an Eclipse user, you can still use the Groovy Eclipse plugin, or Sun's work in progress NetBeans plugin for Groovy and Grails.

InfoQ publishes an article detailing the novelties of this new version in more depth.

You can also listen to the interview of Groovy Project Manager and G2One VP Technology Guillaume Laforge that was recorded at QCon 2007, in March, in London, or read G2One's team interview at JavaLobby.

I would like to thank everybody who was involved in this release in a way or another: the Groovy developers for their hard work, patch and documentation contributors, users reporting bugs or requesting new features or improvements, book authors.

Several well-known companies have put great efforts in helping us making Groovy what it is today:

  • IBM: Eclipse plugin improvements and upgrade to support this latest version of the language,
  • Oracle: JMX support improvements to call remote beans as if they were local,
  • Sun: Rooms for our developer meetings, and a wonderful 8-core 8-CPU machine for our high-load concurrency testing,
  • JetBrains: for the joint java/groovy compiler & their awesome plugin,
  • JBoss: for their help on ironing out our support for annotations and generics.

It would be impossible to list everybody, but you're all part of this effort, and you made the success of Groovy and the quality of this new milestone. Thanks and well done to you all!

You can read the detailed JIRA release notes of the changes since the last release candidate.

The latest Groovy + Maven2 integration is ready for mass-consumption and overwhelming build joy.

Some of the new goodies:

  • Completely rewritten core, which allows the Groovy runtime version to be changed.
  • Brand new stub-generator that preserves Javadocs (so the standard maven-javadoc-plugin works with it).
  • org.codehaus.mojo:groovy-maven-plugin has been crafted to provided a link to the org.codehaus.mojo.groovy:groovy-maven-plugin, which means that mvn groovy:shell works!
