**If you use `@ionic-native/google-maps`, please tell the package.json (only `@ionic-native/core` and `@ionic-native/google-maps` are fine mostly)**

```

@ionic-native/core: “4.7.0”,  
@ionic-native/google-maps: “^4.7.0”

When I build with ionic cordova build android [--prod] It reports this error:

`Could not get unknown property 'PLAY_SERVICES_VERSION' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.`

If I install the plugin cordova-android-play-services-gradle-release with the variable --variable PLAY_SERVICES_VERSION=11.8.0

It reports only the ANDROID_SUPPORT_V4_VERSION error. I have already tried to install the plugin [cordova-android-support-gradle-release](https://www.npmjs.com/package/cordova-android-support-gradle-release) but this plugin not works

**Expected behavior:**
App compiles without problems

Any idea?

Yes. Cordova Google Maps plugin \> 2.1.1 uses environment variables to asign version dependencies like google play services.

Cordova includes support to this variables since 7.1.1 version. In my case I used 7.0.1 and upgrading to cordova 8 solves the problem.
