火基地和谷歌播放服务无法解决异常 [英] fire base and google play services can't resolve exception

问题描述

我正在尝试使用以下gradle文件构建应用程序:

I'm trying to build my application with the following gradle file:

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
buildToolsVersion '28.0.0 rc1'

defaultConfig {
    applicationId "com.wallet"
    minSdkVersion 17
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
    vectorDrawables.useSupportLibrary true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
dataBinding {
    enabled = true
}
dexOptions {
    javaMaxHeapSize "4g"
}
lintOptions {
    abortOnError false
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
androidTestImplementation('com.android.support.test.espresso:espresso- 
core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-

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

项目的gradle文件:

project' gradle file:

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'
        classpath 'com.google.gms:google-services:4.0.1'

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

allprojects {
    repositories {
        jcenter()
        maven { url 'https://jitpack.io' }
        maven { url 'https://maven.google.com' }
        maven { url "https://dl.bintray.com/krazykira/maven" }
        google()
    }
}

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

我遇到以下错误:

Failed to resolve: play-services-base
Failed to resolve: play-services-ads-identifier

当我将play-services-base版本更改为15.0.0时，此错误已修复，但当我对play-services-ads-identifier执行相同操作时，则没有更改.无论如何，我是否可以了解问题所在，或者如何使该应用程序与当前版本一起使用?

when I change the play-services-base version to 15.0.0 this error is fixed but when I do the same for play-services-ads-identifier there's no change. Is there anyway for me to understand what is the problem or how can I make the app work with the current versions?

任何帮助将不胜感激3>

Any help would be appreciated 3>

推荐答案

由于我不知道的原因，google()必须在存储库列表中的jcenter()之前出现，如

For reasons unknown to me, google() must appear before jcenter() in the list of repositories, as is shown in the documentation.

buildscript {
    repositories {
        google() // <== CHANGED
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'
        classpath 'com.google.gms:google-services:4.0.1'
    }
}

allprojects {
    repositories {
        google() // <= CHANGED
        jcenter()
        maven { url 'https://jitpack.io' }
        maven { url 'https://maven.google.com' }
        maven { url "https://dl.bintray.com/krazykira/maven" }
    }
}
