Could not open settings generic class cache for settings file

Help/Discuss

I am using svelte to build a web app and will use capacitor to build into an android apk.

I have ran the following commands:

npm install @capacitor/cli @capacitor/core
npx cap init
npm install @capacitor/android

npx cap add android
npx cap copy android

cd android
./gradlew assembleDebug

However I get this error:

Could not open settings generic class cache for settings file '/mnt/Windows10/Users/joe/Desktop/some programs/Projects/wheres_my_car/android/settings.gradle' (/home/joe/.gradle/caches/8.2.1/scripts/er3mpjmafek4dm6hp4m5k0z22).
> BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 66

BUILD FAILED in 417ms

I am not too sure if I am missing something from capacitor etc?

What you miss is Compatibility Matrix.
You try to run a Gradle 8.2.1 build using Java 22 and that is not supported.
