cordova-android-firebase-gradle-release 
Cordova/Phonegap plugin for Android to align versions of the Firebase library components specified by other plugins to a specific version.
Table of Contents
Purpose
TL;DR: To prevent build failures caused by Cordova plugins including different versions of Firebase library components.
To resolve these version collisions, this plugin injects a Gradle configuration file into the native Android platform project, which overrides any versions specified by other plugins, and forces them to the version specified in its Gradle file.
If you're encountering similar problems with the Android Support or Play Services libraries, checkout the sister plugins:
Requirements
This plugin requires cordova@8+ (CLI) and cordova-android@7+ (Android platform).
Since the plugin uses hook scripts it will not work in Cloud Build environments such as Phonegap Build.
Installation
# override using default component versions
$ cordova plugin add cordova-android-firebase-gradle-release
## override using custom component versions
$ cordova plugin add cordova-android-firebase-gradle-release --variable firebase-core=17.0.0 --variable firebase-messaging=19.0.0

Default version
By default, this plugin pins a recent major version of each of the Firebase library components.
You can see what the currently pinned versions are by looking at the <preference>'s in the plugin.xml.
Other versions
You may want to specify a version the Firebase library components - see here for a list recent versions.
Library component versions are specified in the Android build as Gradle artifacts in the format packageId:componentId:versionNumber, for example com.google.firebase:firebase-core:17.0.0.
To override the default version when installing this plugin, specify a plugin variable where then variable key is the component ID and the value is the version number.
For example, if you want to install v17.0.0 of the Firebase Core library component, you'd specify the version via the variable:
cordova plugin add cordova-android-firebase-gradle-release --variable firebase-core=17.0.0
You can also specify the the overrides directly in the config.xml and this plugin will find them, for example:
<plugin name="cordova-android-firebase-gradle-release" spec="^4.0.0">
<variable name="firebase-core" value="17.0.0" />
</plugin>
Or in the package.json, e.g.:
{
"cordova": {
"plugins": {
"cordova-android-firebase-gradle-release": {
"firebase-core": "17.0.0"
}
}
}
}
}
Note: the plugin is case-insensitive to the component ID so firebase-core or FIREBASE-CORE will both work.
