flex Error: unable to resolve resource bundle "core" for locale "en_US"

I'm trying to include a swc library in a flowplayer plugin I'm building, but when I include this swc it is referencing some of the core framework resource bundles. But for some reason the mxmlc compiler is not finding them.

I've added the -include-resource-bundles=core,effects,skins,styles to the mxmlc arguments, but I'm still getting this error for each core, effects, etc:

Error: Unable to resolve resour开发者_StackOverflow社区ce bundle "core" for local "en_US".

I have the .properties files in my flexsdk folders.

Is there some other flag I'm missing for the mxmlc compiler to find these?

Maybe this is a just an artifact of the flowplayer ant scripts, but I was able to solve this by including the path to the bundles explicitly in the mxmlc_bin call:

<arg line="-source-path @{src} ${mxmlc-library-path} ${mxmlc-sources} ${flex3dir}/frameworks/projects/framework/bundles/en_US/src" />
