Hello! Can you please share which Eric Evans' book are you

talking about? (just curious, haven't read it and want check it) Is this "Domain-Driven Design Reference: Definitions and Pattern Summaries" 2014 ? Can you please give your impression about this book?

I'm working with grails but not with python or ruby background. I'm there right from the java world.
Here's the tech stack:
groovy = java se + groovy syntax + groovy features
spring boot = java web framework = java se + web framework
grails = spring + groovy

In this list, you may omit only spring to some extent, since grails actually does all the spring's work. However, it uses spring framework as its implementation backbone.
Thus, if you want to be proficient with grails, you should learn tech stack in this order: java core ("java se"), groovy, spring, grails.

Groovy uses lots of java features and actually you can't write groovy code confidently without knowing java.

Regarding resources. Personally, I prefer books since they are methodological. Here's the list
* java se - ask here or in any other java community, there are tons of resources for java se. My favorites are Bruce Eckel or Horstman for core java, after that you go with "Java concurrency in practice" by Brian Goetz, and then "Effective Java" by Joshua Bloch. Eckel's book probably is outdated these days but it may ok if you're going to work with Grails3 (it runs on java 8).
* groovy - "groovy in action" - is the most brilliant book for groovy. Also the official documentation is awesome. Also google for "mrhaki groovy" blog posts - it's available online, but also you can support him and buy all the collection in single pdf (there are also same collections for grails and gradle, and the budle of all three).
* spring - probably "spring in action" and something spring boot related, ask here or in any java community
* grails - "grails in action" by Glen Smith and Peter Ledbrook is great, probably the best one matching your request, but it's for grails 2.x. Anyway, it greatly explains grails philosophy. I've also bought 3.x books by Eric Hengelson and Christian Olaru, but like them less than "grails in action". However, the most important thing I found there is a nice example of how to use grails plugins. Again, "mrhaki grails" blog posts are awesome. And don't underestimate grails official documentation, it's really great, but is more a reference and is useful after you've read something more methodological and comprehensive.
+ Also note, that GORM (Grails orm) and gsp have their own dedicated docs. One for GORM is especially comprehensive and useful, more than in any mentioned book.
+ Since GORM is built upon Hibernate it's really nice to learn it. At least after you read gorm chapters of any grails book, check these (google for part 2 and 3):
https://spring.io/blog/2010/06/23/gorm-gotchas-part-1/

+ "spock" and "geb" official docs are awesome, never needed more than that.
