一、報錯信息

編譯 VirtualAppEx 源碼時 , 報如下錯誤 :

Gradle 'VirtualAppEx-master' project refresh failed Error:Connection timed out: connect

使用

gradlew assembleDebug --stacktrace

命令 , 查看詳細報錯信息 :

二、解決方案

---

下面這種依賴庫的配置方式無法獲取到 Gradle 編譯相關依賴庫 ;

repositories {jcenter()maven {url 'https://maven.google.com/'name 'Google'}}

添加 google() 和 mavenCentral() 即可 ;

repositories {jcenter()google()mavenCentral()maven {url 'https://maven.google.com/'name 'Google'}}

完整的 build.gradle 構建腳本如下 :

buildscript {repositories {jcenter()google()mavenCentral()maven {url 'https://maven.google.com/'name 'Google'}}dependencies {classpath 'com.android.tools.build:gradle:3.0.1'classpath 'com.android.tools.build:gradle-experimental:0.11.0'// NOTE: Do not place your application dependencies here; they belong// in the individual module build.gradle files} }allprojects {repositories {jcenter()google()mavenCentral()maven {url "https://jitpack.io"}maven {url 'https://maven.google.com/'name 'Google'}} }task clean(type: Delete) {delete rootProject.buildDir }

修改完畢后可以正常編譯 ;
