How to fix 'Execution failed for task ':app:compileDebugKotlin'' | jvm target compatibility error.

Solution for Kotlin project compilation error "Execution failed for task ':app:compileDebugKotlin'".
'compileDebugJavaWithJavac' task (current target is 1.8) and 'compileDebugKotlin' task (current target is 17) jvm target compatibility should be set to the same Java version.

Solution:-
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = JavaVersion.VERSION_1_8
}

#java
#kotlin
#androidstudio

It's interesting because your version of Studio has a Gradle Version and Gradle Plugin Version whereas mine does not. So I had no shortcut. I have needed to create a new project and take all my files across to the new project. It seems to be a design fault with Studio and a reason why a new version of Studio would come out -- so that settings for switching the Gradle Version etc. could be included. Thank you for this content and for trying to assist 😊... Also, I tried your latter solution which would've been perfect, but the same error message appears. It seems to mean that despite the setting-adjustments, that there is an underlying reliance on the 1.8 that keeps coming up.

> 'compileDebugJavaWithJavac' task (current target is 1.8) and task (current target is 18) jvm target compatibility should be set to the same Java version. always show error

Thank you my life saviour!!
However, I find it is quite weird that by default my build gradle setting has set both to java version 1.8 but it still throws errors.
When changing them to version 17 then it resolved.
