最近我安装了 Android studio 3.0.1 ,并尝试运行一个简单的" Hello World"项目在Gradle项目同步的第一个常见步骤我遇到了这个错误并且它结束了: 无法解析com.android.support:appcompat-v7:26.0.1。 它似乎也是导致 Maven 的常见错误,并且应该通过在build.gradle项目文件中添加以下代码来解决,如https://developer.android.com/topic/libraries/support-library/setup.html中所述

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

这是我的顶级build.gradle文件:

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'
    // 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
}

这是我的app / build.gradle文件:

apply plugin: 'com.android.application'
android {
compileSdkVersion 26
defaultConfig {
    applicationId "com.example.renayati.myapplication2"
    minSdkVersion 15
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary= true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.0.1'
    implementation 'com.android.support:design:26.0.1'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.android.support:support-vector-drawable:26.0.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:0.5'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:2.2.2'
}  

我也是

1.从我的项目根文件夹中删除gradle并再次重建项目,但它没有工作......

2.评论下面这三行,但仍然是相同的错误信息。

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:0.5'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:2.2.2'

没有工作......

我搜索的更多,但我只是听到相同的答案。有人在这帮助我吗?

buildToolsVersion "26.0.1"放在gradle build中的compileSdkVersion下面。并下载26.0.1存储库
