cat't import domain class from grails plugin into main prject -

i have grails plugin has it's own domain classes , default controllers. plugin works fine, can't seem import plugin domain classes service in main project.

//plugin domain  package us.cscheduler   class calendarentry{    //...  }  

if run loop through artefacts available in main project

//in main project crosscalendarservice def grailsapplication=holders.getgrailsapplication();     (cls in grailsapplication.domainclasses) {            println cls.getfullname();           //does output 'us.cscheduler.calendarentry'  } 

i confirm have calendarentry artefact. when try use it

  //in main crosscalendarservice  def importentry(calendarentry ca) 

i unable resolve class error. i've tried variety of import variations like

import us.cscheduler.calendarentry//unable resolve import grails.plugin.us.cscheduler.calendarentry//unable resolve import grails.plugin.cscheduler.calendarentry//unable resolve 

but none of them seem path grails expecting.
