[Cmd 7.0] NPE in sencha generate app

[sksoft]

When I try to generate new classic app using downloaded ExtJS SDK with the following command:

sencha generate app -ext -classic AdminApp ./AdminApp

I got the following NPE:

java.lang.NullPointerException

I've downloaded latest version of ExtJS (7.0.0.156), Cmd (7.0.0.40). Also I've added the following two lines in sencha.cfg (in Cmd installation folder) in order to use downloaded files when generating my app:

framework.dir=C:/Web/Sencha/ext-7.0.0
framework.key=ext

Diagnostic info from error.log:

I'll be glad to hear any ideas...
