sencha cmd - Why do I get an error when upgrading from ExtJS 4.2.1 to ExtJS 5? -


i executed following specified in extjs 5 upgrade guide:

and got output error:

sencha app upgrade -ext sencha cmd v5.0.0.160 [inf] downloading ext package... [inf] source file : http://cdn.sencha.com/cmd/packages/e....0.970/ext.pkg [inf] downloading : ....................

and when execute "sencha app upgrade" this:

sencha cmd v5.0.0.160 [inf] upgrading application [inf] upgrading sdk @ c:\atlantis\amc\gui\src\main\ext [inf] updating application , workspace ext js 4.2.1.883 / cmd 3.0.0.250 [err] org.mozilla.javascript.wrappedexception: wrapped java.lang.nullpointerexception (anonymous#336) [err] application last modified older version of sencha cmd (0.0.0.0) current 5.0.0.160. please run "sencha app upgrade" update 5.0.0.160.

try adding app.cmd.version=3.0.0.250 (or whatever version of cmd were running) app's sencha.cfg file. works me.
