cloud package build with FCM plugin error

I’m facing error when run “ionic package build” my app that using FCM (Firebase Cloud Messaging) plugin.

Error: cordova-plugin-fcm: You have installed platform android but file 'google-services.json' was not found in your Cordova project root folder.

Here’s my ionic info:

Cordova CLI: 6.4.0 
Ionic Framework Version: 3.0.1
Ionic CLI Version: 2.2.3
Ionic App Lib Version: 2.2.1
Ionic App Scripts Version: 1.3.0
ios-deploy version: 1.9.0 
ios-sim version: 5.0.12 
OS: OS X El Capitan
Node Version: v6.9.4
Xcode version: Xcode 8.0 Build version 8A218a

I have already put google-service.json in the root of project folder and inside platforms/android folder.

Is someone facing the same issue with me?

This will probably not work with ionic package as these files are not uploaded. Is there a way for the plugin to work without this file?

What exact plugins are you using for FCM?
