The Groovy development team is happy to announce the release of a third beta for Groovy 2.4. This release contains various bug fixes and minor improvements. I’ll highlight the fact that you can now use multiple labels on your statements (instead of just one). With beta-3 now, many of the unneeded synthetic methods generated by Groovy are not generated anymore, reducing the number of methods nicely yielding smaller bytecode. This is of particular interest for Android developers limited in the overall number of methods used in Android applications. Read more...

On the Groovy mailing-list, we had an interesting question about how to disable annotations like @Grab, to prevent users from downloading third-party dependencies. There are a few possibilities for that, but my favorite was to create a global AST transformation that would generate a compilation error if the @Grab annotation is found on an import. I created a first small prototype within a script, but I used an injected local transformation to get everything working with a simple script. Read more...
