Bug Report

Problem

What is expected to happen?

The build to complete successful.

What does actually happen?

The build fails with an error of Class 'kotlin.Unit' was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.7.1, expected version is 1.5.1

Information

Some more context in #1543.

This started happening for two of our developers in the last week or so. I was not able to lock down the exactly change which triggered this, but it is a tooling change rather than code changes since we have not done any cordova package upgrades in the last few months.

The workaround is to add <preference name="GradlePluginKotlinVersion" value="1.7.22"/> to your config.xml.

Command or Code

Attempt to build android, either via the command line or android studio.

Version information

cordova@11
cordvoa-android@11
MacOS Ventura
Android Studio 2022.1.1 Patch 2

Checklist

• I searched for existing GitHub issues
• I updated all Cordova tooling to most recent version
• I included all the necessary information above

I can confirm adding <preference name="GradlePluginKotlinVersion" value="1.7.22"/> to your config.xml as @kbrownlees suggested worked, thanks!
