由于 Gradle 中的 Kotlin 版本不匹配，Flutter 构建失败

Question

更新到新的 Kotlin 版本后 Flutter 构建失败 我正在开发一个 Flutter 项目，在更新一些依赖项后，我遇到了构建错误。我使用的是最新版本的 Kotlin，当我运行 flutter build apk 时，它失败并出现以下错误：

e: C:/Users/Moham/.gradle/caches/transforms-3/1a36c150372f3edd1303b1fe7aa45a27/transformed/fragment-1.7.1-api.jar!/META-INF/fragment_release.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.8.0, expected version is 1.6.0.
Running Gradle task 'assembleRelease'...                          251.8s

似乎表明 Kotlin 版本不兼容。这是我的 build.gradle 中的设置

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

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

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

设置.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 "7.3.0" apply false
    id "org.jetbrains.kotlin.android" version "2.0.20" apply false
}

include ":app"

看来我需要更新 Kotlin Gradle 插件，但我不确定如何正确解决这个问题。我还在 C: lutter_app\lklk-live ndroid uild.gradle 中看到了更新插件的建议，但我已经将 kotlin_version 设置为最新版本（2.0.20）。

有人遇到过这个问题吗？如何解决 Kotlin 版本不兼容问题？ Flutter（频道稳定，3.24.0，在 Microsoft Windows [版本 10.0.19045.2486]，区域设置 en-US）

将此代码添加到您的

android/build.gradle

:

buildscript {
    ext.kotlin_version = '2.0.20' //Your preferred Kotlin Version
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}
