Package Name Change not Recognized

Hi, I'm working on a project using Subversion.  A change was made to a package name from camel case to no capital letters ie: packageName to packagename.  When I try to build the project I continually get:

SEVERE: Unable to load annotated class: com.packageName, reason: java.lang.NoClassDefFoundError: com/packageName (wrong name: com/packagename)

I have tried cleaning the exploded artifact, invalidating caches, deleting Intellij cache folder on the file system, deleting and re-creating the module.  Any tips - I'm using Ultimate 10.5
