Android Studio Kapt error: app:kaptGenerateStubsDebugKotlin compileDebugJavaWithJavac jvm target compatibility should be set to the same Java version

Question

Execution failed for task ':app:kaptGenerateStubsDebugKotlin'.

'compileDebugJavaWithJavac' task (current target is 1.7) 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

Environment:

Android Studio Giraffe | 2022.3.1 Patch 2 Gradle: 8.0 Gradle JDK: JetBrains 17.0.6 Kotlin: 1.8.10

compileSdk = 34 targetSdk = 34

 compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_7
        targetCompatibility = JavaVersion.VERSION_1_7
    }
    //tried both of the below
    kotlin{
        jvmToolchain(17)
    }
    /*kotlinOptions {
        jvmTarget = "17"
    }*/

composeOptions { kotlinCompilerExtensionVersion = "1.4.3" }

Plugins:

plugins {
  id("com.android.application") version "8.1.2" apply false
  id("org.jetbrains.kotlin.android") version "1.8.10" apply false
  id ("dagger.hilt.android.plugin") version "2.48" apply false
  kotlin("kapt") version "1.8.10" apply false

}

Similar errors were discussed, for example, here. But in my case, both are set to the same version - 17! I did try setting to 18 and changing the Gradle JDK to Amazon Coretto 18, no difference.

Per compiler compatibility, no compatibility issues between kotlin compiler 1.4.3 and kotlin 1.8.10.

What error says that you are using version 1.7 rather 17

Here is your mistake. you have declared 1.7

compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_7
        targetCompatibility = JavaVersion.VERSION_1_7
    }

But the Change is just remove _ in between 1 and 7 and your problem must solved.

compileOptions {
        sourceCompatibility = JavaVersion.VERSION_17
        targetCompatibility = JavaVersion.VERSION_17
    }

It's typo error I could say. Hope it solves your problem.
