By now, most of the setup commands are optional (see FORGE-1686 or FORGE-1479). Forge takes the setup by default if not specified. Same should happen with scaffolding. Today, to scaffold a JSF application, we need to execute :

scaffold-setup
scaffold-generate --targets org.test.model.* ;

It would be better if, following the same principals, the setup command would run as a default, and only this would be needed :

scaffold-generate --targets org.test.model.* ;

If we want to explicitelly scaffold an AngularJS app, then we would go :

scaffold-setup --provider AngularJS ;
scaffold-generate --targets org.test.model.* ;
