如何从插件覆盖 Cordova 项目的 gradle.properties？

Question

I'm developing a Cordova plugin for Android. It uses a couple of dependencies like:

com.android.tools.build.gradle:4.1.1

com.google.gms:google-services:3.2.0

So far it looks like (but please correct me if I'm wrong) they're imported properly if I add them to plugin.xml , which in turn inserts them into the project's AndroidManifest.xml like this:

<framework src="com.android.tools.build:gradle:4.1.1" />
<framework src="com.google.gms:google-services:3.2.0" />

At least this isn't throwing a build error. I do get another error though:

This project uses AndroidX dependencies, but the 'android.useAndroidX' property is not enabled. Set this property to true in the gradle.properties file and retry.

And the problem is that a Cordova plugin has no gradle.properties file. The Cordova project has one, but changing android.useAndroidX and android.enableJetifier in it manually doesn't seem to help: the build will still throw the same error.

The question is: How can I tell Cordova to set these values in gradle.properties to true ? Is there some way to update or overwrite gradle.properties at build time, in a similar way how the contents of plugin.xml are registered in AndroidManifest.xml and a gradle file attached to the plugin gets added to build.gradle ?

Turns out it doesn't need overriding. In the Cordova project's config.xml the following line should be added:

<preference name="AndroidXEnabled" value="true" />
