Question

我的build.gradle文件如下:

应用插件:'com.android.application'

安卓{

compileSdkVersion 26

buildToolsVersion '25.0.3'

defaultConfig {

    applicationId "com.xavier.hello"

    minSdkVersion 15

    targetSdkVersion 26

    versionCode 1

    versionName "1.0"

    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

buildTypes {

    release {

        minifyEnabled false

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

    }

}

依赖关系{

compile fileTree(include: ['*.jar'], dir: 'libs')

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2',

{

排除组:'com.android.support'，模块:'support-annotations'

})

compile 'com.android.support.constraint:constraint-layout:1.0.2'

testCompile 'junit:junit:4.12'

每次都报如下错误:

当我想尝试 Espresso 时遇到了同样的问题。

我已经通过添加解决了

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

到

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