错误：无法找到符号类GoogleAccountCredential

Question

由Android构建失败，出现以下错误 -

Error:(23, 68) error: package com.google.api.client.googleapis.extensions.android.gms.auth does not exist
Error:(60, 20) error: cannot find symbol class GoogleAccountCredential
Error:(79, 19) error: cannot find symbol class GoogleAccountCredential
Error:(218, 22) error: cannot find symbol variable GoogleAccountCredential
Error:Execution failed for task ':app:compileDebugJavaWithJavac'.
> Compilation failed; see the compiler error output for details.

我无法弄清楚这个类属于哪个库。包裹是

com.google.api.client.googleapis.extensions.android.gms.authc.GoogleAccountCredential;

我尝试在构建依赖项中添加所有库。现在看起来像下面 -

dependencies {

compile 'com.google.android.gms:play-services-plus:9.0.2'
compile 'com.google.android.gms:play-services-ads:9.0.2'
compile 'com.google.android.gms:play-services-gcm:9.0.2'
compile 'com.google.android.gms:play-services-maps:9.0.2'
compile 'com.google.android.gms:play-services-auth:9.0.2'
compile 'com.google.android.gms:play-services-base:9.0.2'
compile 'com.google.android.gms:play-services-identity:9.0.2'

compile 'com.google.api-client:google-api-client:1.23.0'


compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.google.code.gson:gson:2.4'

// V2: Endpoints Framework v2 migration
endpointsServer project(path: ':DeviceLocatorBackend', configuration: 'endpoints')
compile 'com.google.api-client:google-api-client:+'
compile 'com.google.http-client:google-http-client-android:1.22.0'
}

必须添加以下依赖项才能使其工作 -

compile 'com.google.api-client:google-api-client-android:1.20.0'
