Enter the name of the domain class in the name field and click Finish. Grails creates the Book domain
class and BookTests, as shown in the following output:

Loading Grails 2.2.4
| Environment set to development.....
| Created file grails-app/domain/bookstore/Book.groovy
| Compiling 1 source files.....
| Created file test/unit/bookstore/BookTests.groovy

Listing 7-8 illustrates the Book class generated by Grails.

Listing 7-8. Book Domain Class Generated by Grails

class Book {

static constraints = {
}
}

The Book class in Listing 7-8 is empty. Now you can complete this domain class as illustrated
in Listing 7-9.
