android - Android Studio-安装Android Studio 3.1.3后gradle无法同步

Question

我已经将android studio更新为3.1.3，升级后，我的gradle不同步，它向我显示此错误:

它不会下载

https://dl.google.com/dl/android/maven2/com/android/tools/build/builder/3.0.1/builder-3.0.1.jar

因此无法同步。

如何手动下载此gradle并将其添加到我的android studio？

编辑:
这是我的 主要gradle 文件。我也尝试使用代理，但不起作用

    buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'


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

allprojects {
    repositories {
        google()
        jcenter()
    }
}

编辑:我的 级gradle :

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "ir.persiandesigners.sima.sima"
        minSdkVersion 14
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:26.0.0-alpha1'
    compile 'com.android.support:recyclerview-v7:26.0.0-alpha1'
    compile 'com.android.support:cardview-v7:26.0.0-alpha1'
    compile 'com.android.support:design:26.0.0-alpha1'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:0.5'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:2.2.2'

    compile 'com.google.android.gms:play-services-gcm:11.8.0'
    compile 'me.cheshmak:analytics:2.0.+'

    implementation 'com.squareup.retrofit2:retrofit:2.4.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
}
repositories {
    maven {
        url 'https://repository.cheshmak.me'
    }
}

更改为应用程序级别的build.gradle文件

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com'
        }

    }
}

并将其添加到您的顶级build.gradle文件中

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

}
