[Hirohumi]

After upgrading the Android Gradle Plugin of the host app to version 8.2.2, flutter run fails with following messages:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':flutter_contacts: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.
  Consider using JVM toolchain: https://kotl.in/gradle/jvm/toolchain

Proposed solution:

Add

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }
}

to android/build.gradle so compileDebugKotlin task will select java 1.8 as its target.

@Hirohumi can you please try again with version 1.1.8?

[Dhana-Krishnasamy]

I still see the same error with version 1.1.8

[joachim-quis]

Hi all - thanks for your patience and the recommended solutions.

This should be fixed in version 1.1.9. If it is not, please let me know, and reopen this conversation.
