title: Unresolved Dependencies Grails 2.3
body: <p>I am unable to run my Grails app because of a dependency problem. BuildConfig.groovy is set to use Maven Central which has the dependencies that Grails cannot find. Any idea why?</p>
  
  <p>This is a project which I only just upgraded to Grails 2.3, if that matters.</p>
