android - 错误 :(26, 13) 无法解析 : com. android.support :appcompat-v7:25. 0.1

Question

Error:(26, 13) Failed to resolve: com.android.support:appcompat-v7:25.0.1
Error:(23, 24) Failed to resolve: com.android.support.test.espresso:espresso-core:2.0

这是我的gradle文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.1"
    defaultConfig {
        applicationId "com.example.jignesh.myapplication"
        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'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.0', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.0.1'
    testCompile 'junit:junit:4.12'
}

您也必须在项目 gradle 文件中使用 maven 存储库 -

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

同步你的项目，它会工作:-)
