Android Packaging: Error generating final archive resources.ap_

I'm currently trying to build a PhoneGap project I've been working on in Eclipse. However, when I try to build and run the project on the Android Emulator, I get the following error...

Error generating final archive: Failed to add /Users/me/Projects/MyApp/bin/resources.ap_ Unknown Android Packaging Problem

I've cleaned the project several times, removed the resources.ap_ file, as well as the contents of the gen directory.

Anything else I can try? Much appreciated.
