cordova-plugin-intercom 10.1.0 fails to compile for Android with Capacitor 3

[abesiemsen]

The latest version of cordova-plugin-intercom (10.1.0) fails to compile for android with Capacitor 3.

Steps to reproduce:

Create a new Ionic project with ionic start, using the 'blank' app template.
Add the android platform: ionic cap add android.
Sync, ionic cap sync, open ionic cap open android, and build in Android Studio, it is successful.

Now, install cordova-plugin-intercom, per https://ionicframework.com/docs/native/intercom.

npm install cordova-plugin-intercom
npm install @ionic-native/intercom
ionic cap sync

Now in Android Studio, the build fails:

FAILURE: Build failed with an exception.

* Where:
Script '/Users/abramsiemsen/Desktop/test/Test/node_modules/cordova-plugin-intercom/src/android/build-extras-intercom.gradle' line: 54

* What went wrong:
A problem occurred configuring project ':app'.
> Could not get unknown property 'cordovaConfig' for project ':app' of type org.gradle.api.Project.

What I expected: A successful build.

Granted, this is almost certainly an issue with cordova-plugin-intercom, but this page suggests letting you know when a cordova plugin is incompatible... so you're welcome? 😉
