问题描述

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，但是没有使用它.如果有解决方案，请告诉我

I am using Android Studio 3.1.3. Gradle build sync failed. I used following method but there is no use of it. If there is any solution please tell me

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

使重启无效&缓存

Invalidate restart & caches

multiDexEnabled true

添加mavenLocal()和mavenCentral()

这是项目级别的 build.gradle 文件:

This is project level build.gradle file:

    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
    }

推荐答案

首先请确保您使用的是

targetSdkVersion 27
compileSdkVersion 27
buildToolsVersion '27.0.3'

和你的gradle像:

And your gradle be like:

// 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:

And also update design implementation like below:

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也存在，您还可以检查支持库

You get this error because com.android.support:design-v7 does not exist it exist without -v7, also you can check support libraries in this link any time to make sure you are using the correct library.
