Gradle Issues with Firebase implementation (buildScript syntax)

Question

I have a React Native (0.68.6) application that I want to implement Firebase push notification. I'm using mac and I wanted to implement & test on android first.

I created Firebase account and created new Project. Also added google-service.json to the [project_folder] > android > app

I cannot build app when I try to add Firebase SDK.

On Firebase it says; if you still use buildscript syntax follow next steps;

1. add following to the dependencies (buildscript > dependencies) in [project_folder] > android > build.gradle

classpath 'PLUGIN_MAVEN_COORDINATES:PLUGIN_VERSION'

2. add plugin to the app level gradle file;

plugins {
    id 'com.android.application'

    // Add the ID of the plugin
    id 'FIREBASE_PLUGIN_ID'
    ...
}

Values;

PLUGIN_MAVEN_COORDINATES : com.google.gms:google-services
PLUGIN_VERSION : 4.4.0
FIREBASE_PLUGIN_ID: com.google.gms.google-services

The changes I made;

[project_folder] > android > build.gradle

buildscript {
...
dependencies {
        ...
        classpath("com.google.gms:google-services:4.4.0")
    }
...
}

[project_folder] > android > app > build.gradle

plugins {
    id "com.android.application"
    id "com.google.gms.google-services"
}

now I cannot build my app with the configurations and it's gave errors following;

FAILURE: Build failed with an exception.

I tried different syntax rules when adding dependency and plugin but no luck.

Can anyone help me? Thanks

I solved the issue by using different syntax and version. If you encounter the same issue, you can follow the steps below;

1. add lines below to the [project_folder] > android > app > build.gradle

    buildscript {
      dependencies {
        ...
        classpath 'com.google.gms:google-services:4.4.0'
      }
    }

2. add lines below to the [project_folder] > android > build.gradle

    plugins {
      id 'com.android.application'
      id 'com.google.gms.google-services'
    }

    dependencies {
    ...
      implementation 'com.google.firebase:firebase-messaging:21.1.0'
    ...
    }

3. clean gradlew

these steps solved the isuue.
