Groovy Weekly #46

My favorite read of the week is definitely Ken Kousen’s tale about Groovy’s Plain Old Groovy Object! Note the releases of the new Groovy Eclipse support and the Eclipse Maven batch compiler. Last but not least, for those of you heading to the Groovy & Grails eXchange conference in London, notice the program of the conference unfolding before your eyes!

Let me also mention the Beaker notebook project, which offers Groovy support for data scientists who want to explore their data sets. And the Spoon.net team which features Groovy support for its Windows containers.

Final word, don’t miss Graeme’s tweets pointing at the Grails 3 scaffolding plugin and code generation APIs!
