1、取消代理
Preferences->Appearance & Behavior->System Settings->Http Proxy
选择 No Proxy
2、取消隐藏代理
关掉隐形代理在mac 上对应的目录:~/.gradle/gradle.properties
3、
Preferences->Build,Execution,Deployment->Gradle,取消“offline work”的勾选,让studio去下载即可。
4、
Preferences->Build,Execution,Deployment->Gradle->Android Studio
取消勾选Disable embedded Maven Repository
5、修改project的bulid.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
在两个repository加了,阿里云的镜像
maven {
url 'http://maven.aliyun.com/nexus/content/groups/public/'
}
再次sync,问题解决,但是把maven去掉,也能正常sync,有点迷,前几步,我的as本来就配好没有修改,猜测可能是wifi不好。。。
