【问题描述】：

运行项目时出现此错误：

无法编译构建文件'H:\StartActivity\build.gradle'。

启动失败： build file 'H:\StartActivity\build.gradle': 28: 在 plugins {} 块之前只允许 buildscript {} 和其他 plugins {} 脚本块，不允许其他语句

    // Top-level build file where you can add configuration options common to all sub-projects/modules.
    buildscript {
        ext.kotlin_version = "1.5.0-release-764"
        repositories {
            google()
            mavenCentral()
        }
        dependencies {
            classpath "com.android.tools.build:gradle:4.2.0"
            classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    
            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
        }
    }
    
    allprojects {
        repositories {
            google()
            mavenCentral()
            jcenter() // Warning: this repository is going to shut down soon
        }
    }
    
    task clean(type: Delete) {
        delete rootProject.buildDir
    }
    plugins {

        kotlinOptions {

已在 Android Studio 4.2.1 中修复：androidstudio.googleblog.com/2021/05/…

【解决方案1】：

buildscript {
    ext.kotlin_version = "1.5.0"
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.2.0"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

将 ext.kotlin_version 更改为 1.5.0 正在工作 :)

【解决方案2】：

你应该在 allprojects{...} 之前移动 plugins{...}

    // Top-level build file where you can add configuration options common to all sub-projects/modules.
    buildscript {
        ext.kotlin_version = "1.5.0-release-764"
        repositories {
            google()
            mavenCentral()
        }
        dependencies {
            classpath "com.android.tools.build:gradle:4.2.0"
            classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    
            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
        }
    }

    plugins {
        id 'org.jetbrains.kotlin.jvm' version '1.5.0-release-764'
    }
    
    allprojects {
        repositories {
            google()
            mavenCentral()
            jcenter() // Warning: this repository is going to shut down soon
        }
    }
    
....
