Android studio 3.2.1 ArtifactResolveException:无法解析配置“:classpath"的所有工件 [英] Android studio 3.2.1 ArtifactResolveException: Could not resolve all artifacts for configuration ':classpath'

问题描述

在我的项目中将 Android Studio 更新到 3.2.1 和 gradle 版本后，我收到以下构建错误.

我已经检查了很多与这个问题相关的问题，但没有运气.

项目依赖 Build.gradle

buildscript {存储库{谷歌()MavenCentral()行家{ url 'https://maven.google.com' }gradlePluginPortal()jcenter()}依赖{类路径 'com.android.tools.build:gradle:3.2.1'//注意:不要将您的应用程序依赖项放在这里；他们属于//在单独的模块 build.gradle 文件中}}所有项目{存储库{谷歌()maven { url "https://jitpack.io" }jcenter()}}任务清理(类型:删除){删除 rootProject.buildDir}

错误

更新

我只是跟着@CoolMind 回答它解决了 gradle 问题，但还有另一个问题是

After I update Android Studio to 3.2.1 and gradle version in my project I am getting following build error.

I have already checked lots of questions related this question but no luck.

Project dependency Build.gradle

buildscript {

    repositories {
        google()
        mavenCentral()
        maven { url 'https://maven.google.com' }
        gradlePluginPortal()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'

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

allprojects {
    repositories {
        google()
        maven { url "https://jitpack.io" }
        jcenter ()

    }
}

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