When building my Capacitor app with revenuecat/purchases-capacitor 9.0.4 I get:

Execution failed for task ':revenuecat-purchases-capacitor:compileDebugKotlin'.
> Error while evaluating property 'compilerOptions.jvmTarget' of task ':revenuecat-purchases-capacitor:compileDebugKotlin'.
   > Failed to calculate the value of property 'jvmTarget'.

Hi @basvdijk, as Toni mentioned, can you confirm which JVM version you're using? And if it's above 17, you may need to use 17 or below instead

I encountered a similar issue while using Capacitor 6 and the Android Studio Koala Feature Drop to build the Android project. I was able to resolve it by adding:

android {
  // other configurations

  kotlinOptions {
      jvmTarget = "17"
  }
}

to the android block in the node_modules/@revenuecat/purchases-capacitor/android/build.gradle file. However, directly modifying files within the node_modules directory is not a recommended practice, as changes may be overwritten on updates. Nonetheless, this solution might serve as a quick workaround or provide a hint for a more permanent fix.
