java - Android Studio : Error (26, 13) Gradle 项目同步失败

Question

每次我创建一个新的 android studio 项目时，都会弹出此错误，并且该项目变得无用。这是我的 gradle 文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.example.dean.youtubeplayer"
        minSdkVersion 16
        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 {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:27.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
}

谁有解决办法？

Answer 1

转到“Gradle Script”并单击“build.gradle”(第一个带有项目而不是模块应用程序的项目。将所有项目行替换为:

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