AS环境配置踩坑经历

遇到的bug

Unable to resolve dependency for ':app@debug/compileClasspath'

这是由于配置文件的依赖是通过Google下载的，然而该下载被墙了！
[解决办法]：

在整个工程的build.gradle中添加以下框内代码：

maven {
        url 'http://maven.aliyun.com/nexus/content/groups/public/'
        }
maven { url 'http://repo1.maven.org/maven2' }

app下的build.gradle配置如下:

buildToolsVersion 需要和你的sdk安装目录 ~\sdk\build-tools文件里面已有的版本对应

android {
    compileSdkVersion 26
    buildToolsVersion '27.0.3'
    defaultConfig {
        applicationId "com.example.administrator.myapplication"
        minSdkVersion 19
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

implementation ‘com.android.support:appcompat-v7:26.+’ 中v7:26.+表示使用的sdk版本

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.+'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:0.4'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:2.2.2'
//    androidTestImplementation 'com.android.support.test:runner:1.0.1'
//    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'


}

若配置后还没解决问题，依然报错

打开 C:/Users/(用户名)/.gradle/gradle.properties
把http代理的配置注释掉，例如：
