I am trying to upgrade a Flex IntelliJ project from 10 to 11.1.1 and am tripping over a flash compile problem. The project has two modules where one is dependant on the other. I've added a build configuration to the libaray module for it to build a swc file and configured the other module's build configuration to use that library. When built the flash compiler gives the error
[CXLiveFFO] (com.cithaeron.cxlive.utils:PagedList) abc bytecode decoding failed.
Web searches indicate this error indicatees is a mismatch between the flex sdks the swf and swc were compiled against. Both modules are set to use flex sdk 4.5.0. I've manually deleted the contents of the out directory, and invalidated the IntelliJ caches and still I get the flex compiler error.
Does IntelliJ/Flex compiler cache files somewhere that the IntelliJ invalidate cache option may not delete?
