Steps to Reproduce

1. Create a simple domain class.
2. Add the following mapping block-

import grails.gorm.hibernate.mapping.MappingBuilder

class User {

    String id

    static mapping = MappingBuilder.orm {
        id generator: "assigned", length: 20
        // Tried below as well
        // id generator: "assigned", maxLength: 20
        // id generator: "assigned", params: [length: 20]
    }
}

3. Run the app and check the table desc user in MySQL.

Expected Behaviour

The id column should be created as VARCHAR(20).

Actual Behaviour

The id column is being created as VARCHAR(255).

• Operating System: macOS Catalina 10.15.7
• GORM Version: 7.0.6
• Grails Version (if using Grails): 4.0.4

To use types and @GrailsCompileStatic annotation, I'm using MappingBuilder.orm in the mapping block.
