Grails project with spring-security-core doesn't build in IDEA, works from command line

Support feedback:

This grails project builds from the command line (with grails war), or by running Build - Make Grails Web Archive, but fails when I run Build - Rebuild Project.

Sample errors (with ... in place of the project name to reduce noise):
```
From one of the plugins:
.../target/work/plugins/asset-pipeline-2.5.0/src/groovy/asset/pipeline/grails/fs/SpringResourceAssetResolver.groovy
Error:(21, 1) Groovyc: unable to resolve class asset.pipeline.GenericAssetFile

And from one of my groovy classes:
.../src/groovy/.../SecurityUtils.groovy
Error:(4, 1) Groovyc: unable to resolve class grails.plugin.springsecurity.SpringSecurityService
```
What might cause this?

Created a new grails project - Rebuild Project worked without any errors.
Added this dependency to BuildConfig.groovy, which caused it to fail:
compile ":spring-security-core:2.0-RC5"

It still builds with 'grails war'.

Added a number of other dependencies from my project, many of which also failed.

The very barebones project is attached - just dependencies added, no other code.

Start with the attached barebones Grails project and its BuildConfig.groovy dependency on spring-security-core:2.0-RC5. Compare IntelliJ IDEA's Build - Rebuild Project with the successful grails war command, focusing on the unresolved asset.pipeline.GenericAssetFile and SpringSecurityService classes. Done means the project rebuilds in IDEA without these resolution errors.
