Question

I’m not sure why this happened, but when I downgrade grails from 1.4.0 to 1.3.7 it causes this to my jquery plugin when I grails run-app

Have you tried deleting your jquery plugin from ~/.grails/yourproject/plugins and forcing a reinstall?

Also, check application.properties to see if the version did not downgrade properly, I’ve heard rumours of plugins not downgrading properly when you downgrade grails version (has to do with dependency chains or something like that iirc). If your jquery plugin is tagged with M1 that is probably it.
