問(wèn)題描述

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' 

但是在執(zhí)行 Gradle 時(shí)，我得到了

But when executing Gradle I'm getting

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

我從 android 支持設(shè)計(jì)庫(kù)中獲得了支持代碼 并將其添加到新項(xiàng)目中.我將它添加到依賴(lài)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'
}

關(guān)于我做錯(cuò)了什么有什么想法嗎?

Any ideas on what I'm doing wrong?

推薦答案

重要提示:現(xiàn)在可以通過(guò) Google 的 Maven 存儲(chǔ)庫(kù)獲得支持庫(kù).您無(wú)需下載支持SDK 管理器中的存儲(chǔ)庫(kù).有關(guān)詳細(xì)信息，請(qǐng)參閱 支持庫(kù)設(shè)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:為您的應(yīng)用打開(kāi) build.gradle 文件.

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

第 2 步:確保存儲(chǔ)庫(kù)部分包含帶有https:/的 maven 部分/maven.google.com"端點(diǎn).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: 將支持庫(kù)添加到依賴(lài)項(xiàng)部分.例如，要添加 v4 core-utils 庫(kù)，請(qǐng)?zhí)砑右韵滦?

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"
}
