标题: android - 无法解析 : com. android.support :design-v7:27. 1.1

我使用的是 Android Studio 3.1.3。 Gradle 构建同步失败。我使用了以下方法，但没有用。如果有解决办法请告诉我

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

2. 使重启和缓存无效

3. multiDexEnabled true

4. 添加 mavenLocal() 和 mavenCentral()

   这是模块级 build.gradle 文件:

   android {
           compileSdkVersion 27
           defaultConfig {
               applicationId "com.developers.a_g.designapp"
               minSdkVersion 15
               targetSdkVersion 27
               buildToolsVersion '27.1.1'
               versionCode 1
               versionName "1.0"
               multiDexEnabled true
               testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
           }
           buildTypes {
               release {
                   minifyEnabled false
                   proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
               }
           }
       }

               buildToolsVersion '27.1.1'
               versionCode 1
               versionName "1.0"
               multiDexEnabled true
               testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
           }
           buildTypes {
               release {
                   minifyEnabled false
                   proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

这是项目级别的 build.gradle 文件:

    buildscript {

        repositories {

            jcenter()
            google()


            maven {
                url "https://maven.google.com"
            }
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.1.3'
        }
    }

    allprojects {
        repositories {
            google()
            jcenter()
        }
    }

    task clean(type: Delete) {
        delete rootProject.buildDir
    }

Best Answer-推荐答案

首先确保您使用的是:

targetSdkVersion 27
compileSdkVersion 27
buildToolsVersion '27.0.3'

你的毕业典礼是这样的:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        //..
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        //..
    }
}

并且还更新设计实现如下:

implementation 'com.android.support:design:27.1.1'

你得到这个错误是因为 com.android.support:design-v7 不存在它没有 -v7 存在，你也可以检查支持库 in this link随时确保您使用的是正确的库。

关于android - 无法解析 : com. android.support :design-v7:27. 1.1，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51189234/
