flutter app not building to some kotlin kotlinOptions not being specified

AbdeMohlbi commented 3 weeks ago

Steps to reproduce

when creating a new flutter project using the flutter create project then updating the settings.gradle as follows(i'm using gradle 8.6 ) :

pluginManagement {
    def flutterSdkPath = {
        def properties = new Properties()
        file("local.properties").withInputStream { properties.load(it) }
        def flutterSdkPath = properties.getProperty("flutter.sdk")
        assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
        return flutterSdkPath
    }()

    includeBuild("$flutterSdkPath/packages/flutter_tools/gradle")

    repositories {
        google()
        mavenCentral()
        gradlePluginPortal()
    }
}

plugins {
    id "dev.flutter.flutter-plugin-loader" version "1.0.0"
    id "com.android.application" version "8.3.2" apply false
    id "org.jetbrains.kotlin.android" version "1.9.23" apply false
}

include ":app"

i'm getting this error :

Expected results

well it supposed to work without any issues (this was my config always for flutter 3.19.6 and it always worked even with 3.19.5) i've seen : stackoverflow,and this video so after doing that i could run the app normally by updating the app/build.gradle like that :

plugins {
    id "com.android.application"
    id "kotlin-android"
    // The Flutter Gradle Plugin must be applied after the Android and Kotlin Gradle plugins.
    id "dev.flutter.flutter-gradle-plugin"
}

android {
    namespace = "com.AbdeMohlbi.todo_app"
    compileSdk = flutter.compileSdkVersion
    ndkVersion "25.1.8937393"

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
// here
    kotlinOptions{
        jvmTarget=JavaVersion.VERSION_1_8
    }
// here
    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId = "com.AbdeMohlbi.todo_app"
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
        minSdk = flutter.minSdkVersion
        targetSdk = flutter.targetSdkVersion
        versionCode = flutter.versionCode
        versionName = flutter.versionName
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig = signingConfigs.debug
        }
    }
}

flutter {
    source = "../.."
}

my question is should the minimal tempalte app trigger this kind of error ? if this is the case i guess this block need to be added to the app/build.gradle file

Actual results

this error apears :

Thanks for filing the issue. I also can reproduce this on a new project created with Flutter master channel, it doesn't occur with Flutter stable 3.19.6.

@huycozy Have u tried my fix has it work ?

huycozy commented 3 weeks ago

Yes, adding kotlinOptions back can make it works

reidbaker commented 3 weeks ago

@flutter/android-reviewers FYI @bartekpacia fyi.

I think in general we will probably either remove or bump the java source compatibility from 1.8 to 11 or 17.

I don't know if this is related but i'm using jdk 21

AbdeMohlbi commented 3 weeks ago

@gmackall i suggest this

kotlinOptions {
        jvmTarget = '1.8'
    }

also something weird but works(performs faster and i don't know why):

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile.class){
        kotlinOptions {
            jvmTarget = "1.8"
        }
    }

@AbdeMohlbi I think we should keep this issue open until the linked PR got merged
