I've never done a build before, and I've downloaded the latest Sencha Cmd beta in hopes that I can package this for production.

However, when I try to build I'm getting errors that don't happen with a newly generated 2.1.0rc1 app.

Code:
seth@havoc [~/Work/cb_mobile/app/trunk]
$ sencha app build testing
Sencha Cmd v3.0.0.190
[ERROR]         The following error occurred while executing this line:
/Users/seth/Work/cb_mobile/app/trunk/.sencha/workspace/plugin.xml:2: Cannot find /Users/seth/Work/cb_mobile/app/trunk/.sencha/workspace/${framework.config.dir}/plugin.xml imported from /Users/seth/Work/cb_mobile/app/trunk/.sencha/workspace/plugin.xml
I'm guessing this is because the older SDK doesn't have the proper config variables set. Can someone walk me through a build process please?
