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，但没有使用它。如果有解决方案，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()

这是模块级别的 build.gradle 文件：

        compileSdkVersion 27

    }

Answer 1

首先确保您使用的是

targetSdkVersion 27
compileSdkVersion 27
buildToolsVersion '27.0.3'

您的喜好就像：

// 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()
        //..
    }
}

并更新如下的设计实现：

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

您会收到此错误，因为com.android.support:design-v7不存在，没有-v7就存在，您也可以随时检查支持库in this link以确保您使用的是正确的库。 / p>

Answer 2

您应该将google()存储库添加到依赖项中

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

Answer 3

不要

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

要做

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

请确保您在下面添加了

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

        }
    }

然后 Clean-Rebuild-Build 。

Answer 4

还要在所有项目部分中添加Maven URL并同步gradle或尝试一一删除外部库，并同步gradle希望对您有所帮助

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。

这是我今天遇到的问题之一。在浪费太多时间找到解决方案之后，这就是工作的重点。当我解决此问题时，我已经忘了实际上在做什么。我真的很奇怪，为什么Google总是在Android Studio中附带损坏的gradle文件。似乎Google工程师甚至他们自己都不知道如何编写正确的gradle，并且在最终发布Android Studio之前也没有人对其进行质量检查。

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'
}

以及项目级别的收益：

// 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
}

无法解决：com.android.support:design-v7:27.1.1
