@omahjoub I had not been able to reproduce your issue.

Can you create from a clean project a minimum reproducible repo of this issue? (with steps)

Steps I took

Create Project, Add Platform, Add Plugin

cordova create androidTest com.foobar.androidTest androidTest && $_
cordova platform add android
cordova plugin add phonegap-plugin-push

Here is a part of my package.json after executing the commands above.

"dependencies": {
    "cordova-android": "^8.0.0",
    "cordova-support-google-services": "^1.1.0",
    "phonegap-plugin-multidex": "^1.0.0",
    "phonegap-plugin-push": "^2.2.3"
  },
  "devDependencies": {
    "cordova-plugin-whitelist": "^1.3.3"
  },
  "cordova": {
    "plugins": {
      "cordova-plugin-whitelist": {},
      "phonegap-plugin-push": {
        "ANDROID_SUPPORT_V13_VERSION": "27.+",
        "FCM_VERSION": "11.6.2"
      }
    },
    "platforms": [
      "android"
    ]

Added the google-services.json file to the root directory of my project.
Updated config.xml to copy google-services.json to the Android platform.

Here is a part of my config.xml file with the update to copy google-services.json to the platform:

<platform name="android">
    <resource-file src="google-services.json" target="app/google-services.json" />
    <allow-intent href="market:*" />
</platform>

Running the build.
```
$ cordova build android --release
```
