Since Maven 3.1 a bug has been fixed that we were relying on for building Flex applications. This caused any transitive dependencies of "rsl", "cache" and "included" scoped dependencies to be omitted from the build. I am currently extending FlexMojos to manually handle the flex scopes. But I am not quite sure about all scenarios. I created a wiki page with a table containig the scopes. The ones I'm quite sure about are bold and blue, the ones I'm not sure about are orange.
