Google 和 Firebase 依赖项在 Android Studio 更新后未解析

Google and Firebase dependencies not resolving after Android Studio update

我最近在 Ubuntu 17.04 上将 Android studio 从 2.1 更新到 2.3.3。此外,我必须将我的 android.support 依赖项从版本 25.0.0 更新到 26.0.1,并将我的 firebase 依赖项从 9.6.1 更新到 11.2.0。我在 SO 上尝试了所有方法都无济于事,包括完全重新成像 ubuntu。所有 google/firebase 依赖项仍然无法解决,所以这一定是我这边的错误。下面是我的 gradle 个文件。

模块build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"

    defaultConfig {
        applicationId "me.myapp.app"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 10
        versionName "0.10.1"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
  'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'

    compile 'com.android.support:appcompat-v7:26.0.1'
    compile 'com.android.support:support-v4:26.0.1'
    compile 'com.android.support:design:26.0.1'
    compile 'com.google.firebase:firebase-core:11.2.0'
    compile 'com.google.firebase:firebase-database:11.2.0'
    compile 'com.google.firebase:firebase-auth:11.2.0'
    compile 'com.google.firebase:firebase-crash:11.2.0'
    compile 'com.google.firebase:firebase-storage:11.2.0'
    compile 'com.google.firebase:firebase-messaging:11.2.0'
    compile 'com.facebook.android:facebook-android-sdk:[4,5)'
    compile 'com.github.amlcurran.showcaseview:library:5.4.3'
}




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

项目build.gradle

    buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'com.google.gms:google-services:3.1.0'

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

allprojects {
    repositories {
        jcenter()
    }
}

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

尝试添加

maven {
            url "https://maven.google.com"
        }

jcenter() 之后

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