ExtJS 6 - Unable to create Native app using command 'sencha app build native'

Question

I am using sencha cmd 6 and trying to build native app with help of - https://docs.sencha.com/cmd/6.x/cordova_phonegap.html

I have generated Ext 6+ universal application using following command:

sencha -sdk /path/to/Framework generate app MyApp /path/to/MyApp

Then I have added following code in app.json -

"builds": {
         "classic": { 
            "toolkit": "classic",
             "theme": "theme-triton",
             "sass": { 
                // "save": "classic/sass/save.json" 
          } 
    },         
"native": { 
            "toolkit": "modern",
             "theme": "theme-cupertino",
             "packager": "phonegap",
             "phonegap": {
                 "config": {
                    "platforms": "ios android",
                    "id": "com.mydomain.MyApp"
                 }
             }
         }
 }

But after running sencha app build android, I am getting following exception -

 BUILD FAILED
 java.lang.NullPointerException
   at org.a
 pache.tools.ant.helper.SingleCheckExecutor.executeTargets(SingleCheckExecutor.java:38)

Also as per suggestion in Developing a PhoneGap application from sencha doc, i have modified app.json with following code -

"builds": {
         "native": {
            "packager": "phonegap",
            "phonegap" : {
                "config": {
                    "platforms": "ios android",
                    "id": "com.mydomain.MyApp"
                }
            }
        }
    }

But after this, following exception is coming on my console -

Failed to resolve dependency Ext.app.Application for file MyApp.Application

BUILD FAILED
com.sencha.exceptions.ExNotFound: Unknown definition for dependency : Ext.app.Application
