Flutter项目build.gradle报错：无法创建:generateLockfiles任务，但应用运行正常

在Flutter项目的android/build.gradle文件中遇到错误：Could not create task ':generateLockfiles'，应用能正常运行，但该错误会影响项目状态。

我的根build.gradle文件内容 #

buildscript {
    ext.kotlin_version = '1.6.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.0.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.13'
    }
}

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

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

task clean(type: Delete) {
    delete rootProject.buildDir
}

flutter doctor -v输出 #

问题原因与解决建议 #

这个问题是版本不兼容冲突导致的，一年前遇到过该问题，当时的解决方案核心是调整依赖版本匹配：

• 重点检查android/build.gradle中的Kotlin版本（ext.kotlin_version = 'x.x.x'），确保它和Android Gradle插件（com.android.tools.build:gradle）版本兼容。升级Kotlin到对应插件推荐的稳定版本即可解决该错误。
