android gradle错误,android – Gradle构建错误：无法解决：

我刚刚下载了

Android Studio并创建了一个新项目,我得到了gradle构建错误：

Failed to resolve: com.android.support.test.espresso-core:2.2.2

和

Failed to resolve: com.android.support.appcompat-v7:25.3.1

在启动android studio作为管理员时重新安装SDK Tools Repository API解决了此错误.

我已经安装了API Level 25,这是我想要构建的并且已经下载了SDK Build-Tools.我也已经下载了支持库

这是我的app文件：

apply plugin: 'com.android.application'

android {

compileSdkVersion 25

buildToolsVersion '25.0.3'

defaultConfig {

applicationId "com.jtsalas.mirrorcontrol"

minSdkVersion 25

targetSdkVersion 25

versionCode 1

versionName "1.0"

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

}

buildTypes {

release {

minifyEnabled false

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

}

}

compileOptions {

sourceCompatibility JavaVersion.VERSION_1_6

targetCompatibility JavaVersion.VERSION_1_7

}

productFlavors {

}

}

dependencies {

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

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

exclude group: 'com.android.support', module: 'support-annotations'

})

compile 'com.android.support:appcompat-v7:25.3.1'

testCompile 'junit:junit:4.12'

}

的build.gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

repositories {

jcenter()

}

dependencies {

classpath 'com.android.tools.build:gradle:2.3.2'

// NOTE: Do not place your application dependencies here; they belong

// in the individual module build.gradle files

}

}

allprojects {

repositories {

jcenter()

}

}

task clean(type: Delete) {

delete rootProject.buildDir

}
