This last week has been filled with the SpringOne2gx conference, which this diary is heavily influenced by, but there are still a lot of news from other sources.

The quality of talks at the conference was high, especially on the Groovy Ecosystem tracks. Cedric did a superb job explaining the internals of the Groovy Compiler, Ben Muschko shared his knowledge on Gradle plugins best practices and Jeff Scott demoed Grails 3 as a foundation for RESTfull webservices microservices as my highlight (amongst many). It might sometimes feel like the 2GX part of the conference is a second class citizen (late tweets on talks, not all talks recorded etc.), but the Groovy Ecosystem does not seem to care.

At the Groovy/Grails Birds of a Feather Session, Marco Vermulen presented the state of the union on the Sdkman project (formerly GVM), and made the official release of 3.0 - and the renaning. Following this, a long discusion on the direction of Groovy, Grails and related technologies, topped with a motivational boosting speach from the CEO of OCI, the new Grails Sponsor. He talked about OCI's long running commitment to Open Source, and I think everyone in the room would agree that Grails is in a better place than a year ago. The future of Grails looks bright! -and the team of OCI Grails developers have already increased from 2 to 6.

At the second day keynote, Graeme rocked the house, and displayed superior live coding skills when developping a component to the keynote app system, and I think this gave a lot of Spring developpers something to to think about. Guillaume also announced that the number of Groovy downloads in 2015 is up to 7.1 million, from 4.5 in the entire 2014!

During the conference, there was a few suggestions for community involvement, which I will pass along:

  • The Grails team recommended a new plugin portal as a community project. The Bintray portal has api endpoints that can be used, and Baruch can be contacted for more info on these.
  • Ben Muschko would gladly hand over maintenance of some of his Gradle plugins
  • The website for GPars could need a hand, from someone with a keen eye on css etc.
  • Cedric mentioned Groovy and Android as an area where contributions are welcome

 

As mentioned above, GVM is now Sdkman, and can be envoked with the sdk command after upgrading. The major release was followed by a couple of bugfixes, and if you experience errors, please raise an issue on github. first you could however try step 4 here. The new website is live and can be found at http://sdkman.io, with credits to @DaiMedina for logo and icon design. The links from Groovy and Grails websites are updated.

Just as SpringOne2gx was comming to a close, Peter created a new episode of the Groovy Podcast, featuring Dan Woods and discussing the release of Ratpack 1.0, the future of Grails an other topics.

Jennifer Strater of the GR8 Ladies is still compiling a list of companies that use Groovy, help her placing your company on the list, if it is not already there and you are using Groovy.

Grooscript has released version 1.2.1, with some fixes and improvements, also upgrading the Gradle plugin. Don't forget to star the Grooscript transpiler on Github!

Antony Jones has shared a bit of code on how to use Geb to test an application that uses AngularJS reliably: https://gist.github.com/antony/270006c36ac7799a5299. The code implements waiting for the angular views to be resolved before attempting assertions.

An example of basic crud for a Ratpack 1.0 application, backed by MongoDB is available here, thanks to Jon DeJong.

Finally, the Grails Slack channel has had an issue with a bit of noise, that hopefully has been resolved now. Burt Beckwith shares Some thoughts on the Grails and Groovy communities, that are worth a read.
