Recently, I had a pleasure to look into several Grails v.2.3+ projects. Despite the fact that I’m not a Grails developer I discovered some anti-patterns. Then I started looking around to find some Grails projects best practices. And they are well known and people still doing mistakes. However, I’ve found several nice resources and I’m (going to quate) quoting them here. I keep references back to original source and use “copy-paste” approach to have aggregated post in single place.
