Reactjs + Capacitor Barcode Scanner: Execution failed for task ':capacitor-barcode-scanner:compileDebugKotlin'

I’m using @capacitor/barcode-scanner in a reactjs project. The web version runs perfectly, but an error occurs for the mobile app ver.

I got this error when running the application

Execution failed for task ‘:capacitor-barcode-scanner:compileDebugKotlin’.
Inconsistent JVM-target compatibility detected for tasks ‘compileDebugJavaWithJavac’ (17) and ‘compileDebugKotlin’ (21).

I tried to change the java version in capacitor.build.gradle file but it will revert back to original when sync.

I also install jdk 17 and jdk 21 to try which one is suitable, but still received the same error.

Here are the solutions I’ve tried:

Link 2
Link 3

Does the error come from Capacitor Barcode Scanner plugin or the Android?

    If you are using latest JDK to your project then you can make changes in build.gradle(app-level) and your project will run successfully.

    compileOptions {
    sourceCompatibility JavaVersion.VERSION_21 // Adjust the version to the one that works for your project.
    targetCompatibility JavaVersion.VERSION_21 // Adjust the version to the one that works for your project.
}

    and

    kotlinOptions {
    jvmTarget = '21'  // Adjust the version to the one that works for your project.
}

    If jdk 21 version not works.
    Then java 17 is always safer option to choose.

    in gradle change source and target compatibility to 17 version for better stability
