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版本之后，我遇到了构建错误.

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

我已经检查了很多与此问题有关的问题，但是没有运气.

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

项目依赖项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
}
