How can I fix Grails error: "No domain class found for name PrivacyOptions. Please try again and enter a valid domain class name"

Question

Add the project name (aka the package name from the first line of the model file) before the model name.

grails generate-all projectname.Class

This is the one that finally worked for me, after an hour of head scratching and googling.

As of 1.2.2 Grails creates artifacts in packages that default to your project name - see http://jira.codehaus.org/browse/GRAILS-5713 So you'd need to run grails generate-all srapp.Srmodel - Burt

it's not projectname.Class , it must be dirname.classname .

eg: your projectname is Helloworld, the directory is "grails-app/domain/helloworld/User.groovy" . so , the command is "grails generate-all helloworld.User" ,but not "Helloworld.User"

Run:

grails clean

and then re-run the generate-all command.

Great help. I faced the same problem following this tutorial that names the project as "trip-planner" and Grails generates the domain directories as '~/trip/planner/' instead of '~/trip-planner/'. Then the generate-all command for a Trip class should be 'grails generate-all trip.planner.Trip'

Just in case someone adds a '-' character to the project name.

Yep... worked for me too. I just prefixed the package name to the class I was trying to generate-all for and it worked. So ...

generate-all racetrack.User

Bit of a pants bug really since all other grails commands do not require a package name to be included :-))
