Issue on cordova 8.0.0 for Cordova Android 7.0.0

[The-Maurya]

For cordova-plugin-background-app version 2.0.2, on updating the app to Cordova 8.0.0 I am getting an error on PhoneGap build for Android app.

I am getting this error in the Log file. This seems to be a Gradle issue.

Is this a plugin issue or am I doing something incorrectly?
