Unknown blueprint: resource in Ember JS

I am new to Ember JS. I am using ember-cli: 3.1.4. I want to create resource file. I have used "ember g resource data". But I cannot create it and the reply is like "Unknown blueprint: resource". Is resource is dropped in the latest version? or still is there? If it is dropped, is there any other methods to use the same feature? It would be better to me, if someone clarifies it as soon as possible. Thank you
