解析失败：com.android.support:design-v7:27.1.1

Question

我正在使用 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

maven { url "https://maven.google.com" }
使重启和缓存无效
multiDexEnabled true

添加 mavenLocal() 和 mavenCentral()

这是模块级别 build.gradle 文件:

        }
    }

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

Answer 1

您应该将 google() 存储库添加到您的依赖项

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

Answer 2

不要

 implementation 'com.android.support:design-v7:27.1.1'
 buildToolsVersion '27.1.1'

做

implementation 'com.android.support:design:27.1.1'
buildToolsVersion '27.0.3'

请确定，您在下方添加了

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

        }
    }

然后Clean-Rebuild-Build.

Answer 3

首先确保您使用的是：

targetSdkVersion 27
compileSdkVersion 27
buildToolsVersion '27.0.3'

而你的 gradle 就像：

// 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()
        //..
    }
}

并像下面这样更新设计实现：

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

你得到这个错误是因为 com.android.support:design-v7 不存在它在没有 -v7 的情况下存在，你也可以随时检查支持库 in this link 以确保你使用的是正确的库.

Answer 4

在所有项目部分添加 maven URL 并同步 gradle 或尝试一个一个地删除外部库并同步 gradle 希望它有帮助

allprojects { repositories { google() jcenter()maven :"http://www.google.com" } }

Answer 5

这是正确的形式
实施 'com.android.support:design:27.1.1'

Answer 6

升级到 Android Studio 3.3 破坏了我所有的项目。

这是我今天运行遇到的问题之一。在浪费太多时间寻找解决方案之后，这里是工作 gradle。当我解决这个问题时，我已经忘记了我实际上在做什么。我真的很想知道为什么 Google 总是在他们的 Android Studio 中发送损坏的 gradle 文件。似乎 Google 工程师甚至自己都不知道如何编写正确的 gradle，也没有人 QA Android Studio 在其最终版本发布之前。

模块级别gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27

    defaultConfig {
        applicationId "com.journaldev.okhttp"
        minSdkVersion 25
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'com.android.support:design:27.1.1'
    testImplementation 'junit:junit:4.12'
    implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1'
    implementation 'com.squareup.okhttp3:okhttp:3.10.0'
}

以及项目级别gradle：

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

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'

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

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

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