I've double, and tripple-checked my build paths, I've even added the SDK's dependencies\lib\bin folder to my PATH environment, but whenever I build my Phonegap project for BB10, I always see the following in the build log:
[exec] [WARN] Build ID set in config.xml [version], but signing key file was not found: author.p12

So the project is pretty much useless.
In the project.properties file, here is the path:
qnx.bbwp.dir=/Developer/SDKs/Research\ In\ Motion/BlackBerry\ 10\ WebWorks\ SDK\ 1.0.4.11
It's the default install path for the SDK.
