检测到 JVM 目标兼容性不一致

Question

我需要从 Visual Studio Code 启动一个小型交付应用程序（使用自己的物理设备），

flutter run

向我抛出此错误：

Launching lib\main.dart on TECNO KJ5 in debug mode...
Building with Flutter multidex support enabled.
You are applying Flutter's main Gradle plugin imperatively using the apply script method, which is deprecated and will be removed in a future release. Migrate to applying Gradle plugins with the declarative plugins block: https://flutter.dev/go/flutter-gradle-plugin-apply


FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':stripe_android:compileDebugKotlin'.
> Inconsistent JVM-target compatibility detected for tasks 'compileDebugJavaWithJavac' (1.8) and 'compileDebugKotlin' (17).

  Consider using JVM Toolchain: https://kotl.in/gradle/jvm/toolchain

这是我的 android/app/build.gradle:

这是我的 android/build.gradle 脚本：

    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }

    subprojects {
        afterEvaluate { project ->
            if (project.hasProperty('android')) {
                project.android {
                    if (namespace == null) {
                        namespace project.group
                    }
                }
            }
        }
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

这是我的 android/settings.gradle:

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
    }
    settings.ext.flutterSdkPath = flutterSdkPath()

    includeBuild("${settings.ext.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 '8.3.0' apply false
    id 'com.android.library' version '8.3.0' apply false
    id 'org.jetbrains.kotlin.android' version '1.9.22' apply false

include ":app"

gradle-wrapper.properties：

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-8.4-all.zip

Android Studio Gradle SDK： 。 我遵循了一些文档packages也做了一些

flutter clean

但同样的错误仍然存在。

Answer 1

尝试改变：

kotlinOptions {
    tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach {
        kotlinOptions.jvmTarget = "17"
    }
}

为此，为所有任务设置目标（因此也为任务

compileDebugJavaWithJavac

）：

kotlinOptions {
    kotlinOptions.jvmTarget = "17"
}
