Getting error: Execution failed for task ':app:kaptGenerateStubsDebugKotlin'. after upgrading to Android Studio Flamingo | 2022.2.1

After updating Android Studio version to 2022.2.1 I started to get this error when trying to compile the project:

Execution failed for task ':app:kaptGenerateStubsDebugKotlin'.
'compileDebugJavaWithJavac' task (current target is 1.8) and 'kaptGenerateStubsDebugKotlin' task (current target is 17) jvm target compatibility should be set to the same Java version.
Consider using JVM toolchain: https://kotl.in/gradle/jvm/toolchain

My gradle: compileSdk 33

defaultConfig {
    minSdk 23
    targetSdk 33

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

    javaCompileOptions {
        annotationProcessorOptions {
            arguments = ["room.incremental": "true"]
        }
    }

    consumerProguardFiles 'proguard-rules.pro'
}

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
    jvmTarget = "1.8"
}

How to fix this error?

Android Studio Flamingo | 2022.2.1

This worked well for Android Studio Giraffe

As per This Toolchain Documentation

Adding this in the app gradle file fixed the issue for me.

compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = "1.8"

    }

    //important
    kotlin {
        jvmToolchain(18)
    }

If you updated Gradle to version 8.0.0 along with the Flamingo 2022.2.1 update, then you need to update the JDK to version 17

You can see the compatibility table here.

The following code in app level build.gradle should solve your problem:

android {
    ...
    compileOptions {
        sourceCompatibilityJavaVersion.VERSION_17
        targetCompatibilityJavaVersion.VERSION_17
    }
    kotlinOptions {
        jvmTarget = '17'
    }
    ...
}
