问题描述

我在 build.gradle(Module:app) 中添加了以下行:

I added the following line to my build.gradle(Module:app):

compile 'com.android.support:design:25.4.0' 

但是在执行 Gradle 时，我得到了

But when executing Gradle I'm getting

Failed to resolve: com.android.support.design:25.4.0

我从 android 支持设计库中获得了支持代码 并将其添加到新项目中.我将它添加到依赖部分，如下所示:

I got that the support code from the android support design library and added it to a new project. I added it to the dependency section as such:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'

    compile 'com.android.support:design:25.4.0'
}

关于我做错了什么有什么想法吗?

Any ideas on what I'm doing wrong?

推荐答案

重要提示:现在可以通过 Google 的 Maven 存储库获得支持库.您无需下载支持SDK 管理器中的存储库.有关详细信息，请参阅 支持库设置.

Important: The support libraries are now available through Google's Maven repository. You do not need to download the support repository from the SDK Manager. For more information, see Support Library Setup.

第 1 步:为您的应用打开 build.gradle 文件.

Step 1: Open the build.gradle file for your application.

第 2 步:确保存储库部分包含带有https:/的 maven 部分/maven.google.com"端点.例如:

Step 2: Make sure that the repositories section includes a maven section with the "https://maven.google.com" endpoint. For example:

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

第 3 步: 将支持库添加到依赖项部分.例如，要添加 v4 core-utils 库，请添加以下行:

Step 3: Add the support library to the dependencies section. For example, to add the v4 core-utils library, add the following lines:

dependencies {
    ...
    compile "com.android.support:support-core-utils:25.4.0"
}
