Groovy JSR 04 released
Dear friends, Just before the Groovy / JSR-241 meeting happening in Paris at the end of the week, we've decided to roll a new version! We're delighted to First of all, a big work has been done to improve the compilation process and the class loading mechanism. Groovy had problems compiling classes with circular references and with script dependencies. Moreover, some imports of inner classes weren't resolved correctly. As those changes are important, those of you embedding Groovy in their applications might face some potential problems. So if you're in that case and are affected with the changes, please tell us how it goes and report JIRA issues with detailed explanations of your integration scenario. Thanks in advance for that, and sorry for any inconvenience. The startup scripts have been improved, and we have replaced clasworlds with a custom implementation. This time, we hope the line-endings of the scripts are fixed correctly. On Windows, we can eventually use more than 8 parameters on the command-line, and you should be able to safely use paths with spaces in them. You can now customize the classpath more easily with the -cp flag. We've upgraded the dependencies on ASM from 2.0 to 2.1. But you can still use the groovy-all-*.jar to escape from jar hell in case you already need those jars on your classpath of your application. Some work was done on the groovy and groovyc Ant tasks. You can now use a debug flag to see what's happening under the hood. And the interaction with Maven 1.0.2 and 1.1 should be nicer when the tasks are reused in that context. On the bytecode generation front, we've properly implemented the support for synchronized blocks. We've also fixed some missing line information, so that stacktraces are as helpful as possible while debugging. Regarding builders, you can now use quoted method names, so that you're able to use hyphens or colons in tags. The support for namespaces has also been improved, and you should be able to spice up your GPath expressions and be able to use our parsers and slurpers on namespaced XML stanzas. A few bugs were fixed with scoping inside closures and nested closures. The two main aspects remaining for Groovy to reach its 1.0 final milestone is to clarify the name resolution and scoping rules. Those two concerns will hopefully be addressed during the Groovy JSR meeting, and we're going to implement these rules as quickly and as thouroughly as possible. Keep in mind that those rules might be a little different than our current rules. However, we hope these rules will be more coherent and closer to what we're used to in Java. The Groovy team and myself are looking forward to hearing about your feedback regarding this new release which should bring even more maturity to our Groovy world. We're getting close to the finish line. And this project would be nowhere without you all, users, developers, affictionados... Thanks a lot for your support, your enthousiasm and your work towards our 1.0 goal. As usual, you'll find the distributions on our download pages: Enjoy, –
