Error Google plus and Firebase


#1

Dear,

I am working with firebase for push notifications in my application and I want to implement authentication with gmail. However, when I install the plugin following the steps

$ ionic cordova plugin add cordova-plugin-googleplus --variable REVERSED_CLIENT_ID=myreversedclientid
$ npm install --save @ionic-native/google-plus

I get an error when running my application on Android (I still can not try on iOS)

:app:transformClassesWithDesugarForDebug
Exception in thread "main" java.lang.IllegalArgumentException

	at com.google.common.base.Preconditions.checkArgument(Preconditions.java:108)

I was finding out and can be due to a conflict between both plugins (Firebase and Google Plus) and asked to modify the versions, however, I do not know how this is done.

My project properties:

target=android-27
android.library.reference.1=CordovaLib
android.library.reference.2=app
cordova.system.library.1=com.android.support:support-v4:24.1.1+
cordova.system.library.2=com.facebook.android:facebook-android-sdk:4.+
cordova.gradle.include.1=cordova-plugin-firebase/alzaisapre-build.gradle
cordova.system.library.3=com.google.gms:google-services:+
cordova.system.library.4=com.google.android.gms:play-services-tagmanager:+
cordova.system.library.5=com.google.firebase:firebase-crash:+
cordova.system.library.6=com.google.firebase:firebase-config:+
cordova.system.library.7=com.google.firebase:firebase-core:+
cordova.system.library.8=com.google.firebase:firebase-messaging:+

Finally solve the problem, I was missing a step when registering the application.
