component-scan base-package cannot resolve

8 gives me a "Cannot resolve package" error on a context:component-scan base-package in one of my Spring 2.5 configuration files. Re-auto-generating the Spring facet doesn't help. When I try auto-complete, it sees that module's library, but not its own source or classes. Of course, 8 doesn't scan those components either. Spring runs fine, however. Are there any ideas how I can fix this?

I have another project with the same kind of component-scan config, but 8 handles it OK. None of the differences seem likely to matter...
