android - 无法同步gradle

Question

当我尝试将 recyclerview 和 cardview 依赖项添加到我的 build.gradle 时，我收到错误消息。这是我的 build.gradle:

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.truewebdev.applytheme"
    minSdkVersion 17
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        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-v7:23.2.0'
compile 'com.android.support.recyclerview-v7:23.2.0'
compile 'com.android.support.cardview-v7:23.2.0'
}

错误信息如下: 如果我尝试安装存储库，我会得到以下信息:

这里有什么问题吗？

您是否从 SDK 管理器下载了 Android 支持存储库？

来自安卓文档:

Make sure you have downloaded the Android Support Repository using the SDK Manager.
