Android studio - 无法解决 : com. android.support :design:26. 0.1 错误

Question

我有一个错误叫做:

 "Failed to resolve: com.android.support:design:26.0.1".

我的android studio版本是3.0 beta 1。

我的gradle文件如下:

apply plugin: 'com.android.application'

android {
compileSdkVersion 26
buildToolsVersion "26.0.1"
defaultConfig {
    applicationId "hojune.example"
    minSdkVersion 17
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.+'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
compile 'com.android.support:design:26.0.1'
}

我想把“设计”放到我的项目中，但是我做不到。我该怎么做？

Answer 1

将此添加到您的项目级别 build.gradle 文件:

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

澄清一下，这应该在 gradle 文件的“allprojects”部分(感谢@tys)
