更新后的 Gradle 错误:com.android.tools:sdk-common

我将 Android Studio 更新到最新版本 (3.1 Canary 8) 并强制将 com.android.tools.build:gradle 更新到版本 3.1.0-alpha08，但同步项目时出现此错误:

I updated Android Studio to the last version (3.1 Canary 8) and mandatorily the com.android.tools.build:gradle to version 3.1.0-alpha08, but syncing the project I get this error:

Could not find sdk-common.jar (com.android.tools:sdk-common:26.1.0-alpha08).
Searched in the following locations:
    https://maven.google.com/com/android/tools/sdk-common/26.1.0-alpha08/sdk-common-26.1.0-alpha08.jar

我四处寻找但没有找到解决方案，有人可以帮我解决这个问题吗?

I searched around but not solution found, can someone help me solve this issue?

buildscript {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0-alpha07'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.1.2'
    }
}

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

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

非常感谢.

更新:这是新的 bukd.gradle(项目):

buildscript {
    repositories {
        google()
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0-alpha08'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.1.2'
    }
}

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

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