Issues with the latest phonegap-plugin-push on PhoneGap Build(PGB)

[ShashankPRS]

We were using phonegap-plugin-push v1.10.0 for push notifications(which was not working),then one of the forums we came to know that the latest version of phonegap-plugin-push v2.2.3 will support for Push notification on PhoneGap Build(PGB). (For more info. https://github.com/phonegap/phonegap-plugin-push#phonegap-plugin-push-) So we updated the Cordova-CLI to 8.1.1, cordova-android-platform version to 7.1.2 and cordova-iOS-platform version to 4.5.5. Then, we installed phonegap-plugin-push v2.2.3. Now we are facing below error while generating the Android build

I am stuck....please help....many thanks in advance
