Created a Grails 3 app backed by MongoDB. I couldn’t get the GORM integration to work right at first. It took me bit of research before finally figuring out what I was doing wrong. Turned out to have to do with interference between Hibernate and the mongodb plugin.

I also created another Grails 3 app, but backed by MySQL this time. This one went a lot smoother.

I can’t get the Grails shell working under Grails 3.1.11. It makes experimenting with the data objects that much more difficult.
