我正在尝试将firebase云存储添加到我的应用程序中.下面是app build.gradle.但它说:无法解决:com.google.firebase:firebase-core:16.0.1.为什么？依赖项中根本没有firebase-core.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.louise.udacity.mydict"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    implementation 'com.google.firebase:firebase-storage:16.0.1'
    implementation 'com.google.firebase:firebase-auth:16.0.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation 'com.google.cloud:google-cloud-storage:1.31.0'
    implementation 'com.firebase:firebase-jobdispatcher:0.8.5'
}

apply plugin: 'com.google.gms.google-services'

我将Android Studio更新到最后一个版本(3.1 Canary 8)并强制将com.android.tools.build:gradle更新到版本3.1.0-alpha08,但同步项目我收到此错误:

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

我四处搜索但未找到解决方案,有人可以帮我解决这个问题吗？

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
}

非常感谢提前.

更新:这是新的bukd.gradle(项目):
