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.
