Gradle构建错误:无法解决:

Question

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:

无法解决:com.android.support.test.espresso-core:2.2.2

和

无法解决: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
}

在 SDK 管理器中，确保您已安装 Android 支持存储库和 Google 存储库并且是最新的。然后，您应该能够在 /extras/android/m2repository 目录的子文件夹中找到相关工件
