Inconsistent JVM-target compatibility detected for tasks 'compileDebugJavaWithJavac' (1.8) and 'compileDebugKotlin' (17). #255

tomcatvr · 2024-02-02T10:26:28Z

Hi, after upgrading to the latest flutter plugin I get this error on compiling the module
Here is my build.gradle config
...
android {
compileSdkVersion 34
ndkVersion flutter.ndkVersion

compileOptions {
    sourceCompatibility JavaVersion.VERSION_11
    targetCompatibility JavaVersion.VERSION_11
}

kotlinOptions {
    jvmTarget = '11'
}

sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}

...

The complete error is
Execution failed for task ':video_compress:compileDebugKotlin'.

Inconsistent JVM-target compatibility detected for tasks 'compileDebugJavaWithJavac' (1.8) and 'compileDebugKotlin' (17).

Dart plugin: 231.9411
Flutter plugin: 77.2.1
Flutter version 3.13.9
Dart version 3.1.5

Thanks
Carlo

After further research it turns out that the error appears useing kotlin >=1.8.0 but as my app uses com.google.gms.google-services which is compiled with a newer version of kotlin, it ends up with: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.9.0, expected version is 1.7.1

So, could you please update the plugin with a new version of kotlin in the build.gradle file with at least ext.kotlin_version = '1.7.10'?
Thanks
Carlo

Encountering the same issue in my project. Seems like this PR should solve this, but there has been no action since October 😬

adigladi · 2024-02-07T15:12:57Z

@tomcatvr check out this comment, seems to be working as a workaround for me at the moment!

@adigladi Thanks very much, it worked!

This looks totally different than what I use (flutter/flutter#125181 (comment))
I use version 34 and 1.8

This is the error I get

@Megatronicus have you found any solution to your problem? I am encountering the same issue and I have been stuck on this for a week, I need help.

cipchk · 2024-08-17T13:33:49Z

try upgrade org.jetbrains.kotlin.android to latest version:

- id "org.jetbrains.kotlin.android" version "1.7.10" apply false
+ id "org.jetbrains.kotlin.android" version "1.9.24" apply false

flyte · 2024-09-30T15:02:40Z

This is what fixed it for me. I recognise that this is probably a hack, covering up the real issue, but maybe it'll get you out of Java Jail:

Top level build.gradle file:

allprojects {
    repositories {
        google()
        mavenCentral()
    }

    // Added this block:
    afterEvaluate { project ->
        if (project.hasProperty("kotlin")) {
            project.tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
                kotlinOptions {
                    jvmTarget = "1.8"
                }
            }
        }
    }
}

Aadii-shah · 2024-11-13T14:27:04Z

this works for me
compileOptions {
// sourceCompatibility JavaVersion.VERSION_17
// targetCompatibility JavaVersion.VERSION_17
coreLibraryDesugaringEnabled true

}

kotlin {
    jvmToolchain(17)
}

derciesto · 2024-11-15T08:22:33Z

Hi, Where did you placed kotlin, inside android or outside?

this works for me compileOptions { // sourceCompatibility JavaVersion.VERSION_17 // targetCompatibility JavaVersion.VERSION_17 coreLibraryDesugaringEnabled true
}

kotlin {

}
