Sencha Cmd Unable to locate 'app.dir' config property from sencha.cfg

Question

I have built a sencha touch app using Sencha touch 2.1.0 and now I am trying to build it using instructions provided here : http://cclerville.blogspot.in/2013/01/sencha-touch-21-phonegap-220-android_3.html

but the build is failing with this error message, can someone help me out?

$ sencha app build package && build/myshop/android/cordova/build
Sencha Cmd v3.0.2.288
[ERR]       Please ensure this command was executed from a valid application directory
[ERR]       Unable to locate 'app.dir' config property from sencha.cfg

sencha.cfg inside my sencha Cmd directory has these entries:

framework.name=touch
framework.version=2.1.0.447
framework.classpath=${framework.dir}/src
# This is the minimum required Sencha Cmd version:
framework.cmd.minver=3.0.0.141
# This is the current version of the Sencha Cmd at the time of this SDK release:
framework.cmd.version=3.0.0.250

Answer 1

Its been long wait for answer so it seems like incompatibility issue to me because I have generated the app using sencha-touch 2.1.0 and its has sencha.cfg at /touch/cmd/sencha.cfg instead of /.sencha/app/sencha.cfg in 2.1.1 apps and its contents are totally different from 2.1.1 file without any reference to ${app.dir} and hence Sencha Cmd cannot use it. Any idea how to build 2.1.0 app? One way I know is to get older version of sencha Cmd.
