如何运行 Grails 脚本并获取域类实例

Question

How to get current application environment in Grails scripts to be able to work with classes and objects like grails console does. My script:

import security.User

List users = User.list()
users.each { User user ->
    print(user.name)
}

And I get an error:

my-script.groovy: 1: unable to resolve class security.User

All other manipulations from Creating an instance of a domain class inside a grails script also does not help.

I see many grails docs are stale and inconsistent.

Grails 3.x removed the run-script command so you have to write your own command. Here is an answer from one of the author of the Grails community:

As an alternative, you can write an ApplicationContextCommand see for example, the schema-export command
