Push Notifications with Firebase Cloud Messaging and Cordova build FCM error Cannot add task ':processDebugGoogleServices' as a task with that name already exists

Ionic Framework ionic-v3
1

Hello, I’m trying to use Push Notifications with Firebase Cloud Messaging and Cordova FCM. My google-services.json located in root folder with config.xml and same file in platforms/android/ folder. With ionic cordova build I got error:

A problem occurred configuring root project ‘android’.

Cannot add task ‘:processDebugGoogleServices’ as a task with that name already exists.

I’ve installs:

cordova plugin add cordova-support-google-services --save
ionic cordova plugin add cordova-plugin-fcm
npm install --save @ionic-native/fcm

and previously by another reason:

cordova plugin add cordova-plugin-googleplus …

Now what I got:

platforms/android/cordova-plugin-fcm/myapp-FCMPlugin.gradle:

buildscript {
	repositories {
            jcenter()
			mavenLocal()
        }

        classpath 'com.google.gms:google-services:3.0.0'
    }
}

Not sure what is wrong, advice would be helpful

Not the solution but I recently had conflict using different version of FCM, that leads me to the following question:

If you redo your edit of platforms/android/project.properties and use explicitly a FCM version (like 11.0.1 or 11.6.2) instead of +, does that help?

Sorry that’s really the only things which popped up in my mind, the rest might be above my knowledges but I hope this could helps a bit

Hello,

I’ve tried both 11.0.1 and 11.6.2 instead of +, and also for directories /plugins/cordova-plugin-fcm/scr/android/FCMPlugin.gradle and plugins/cordova-support-google-services/build.gradle classpath 'com.google.gms:google-services:3.0.0' and 3.2.0' same version separately, and also same for all listed directories labove, but in all cases I got same error

Hi Lado,

Did you ever resolve this error?

Any progress with these issues? I am having similar problems. And all of the other push plugins cause similar build issues with Android. Everything seems to involve some hack somewhere that was not necessary before.

I had a similar issue, and posted my findings and a solution which worked for me over here:
