Q:

Grails / IntelliJ: trouble with simple groovy import?

I'm following Burt Beckwith's (Grails developer and author) use of Heroku as indicated here in Grails book. (See import statement at top of this link -- that's what's giving me problems).
I added the following to BuildConfig.groovy as Burt indicates:
  runtime 'postgresql:postgresql:8.4-702.jdbc3'  // in the dependencies section as described

  compile ':heroku:1.0.1'  // in the plugins section as described.

Then IntelliJ prompted me to update the IDE with the BuildConfig changes, which I did.  I also exited and restarted IntelliJ to see if that might get rid of the import error for:
 import grails.plugin.heroku.PostgresqlServiceInfo

It did not get rid of the import error, which then complains when I do the addition of:
 PostgresqlServiceInfo info = new PostgresqlServiceInfo()

in the Bootstrap class as is shown in the example.  What am I doing wrong / how do I fix this kind of stuff?

A:

In IDEA you need to open Tools | Grails | Plugins, select Heroku plug-in and click Apply Changes.
This will configure a module for the plug-ins and add this module to the dependencies of your application.
