Android Studio:梯度同步失败：无法指向“…”。从服务器接收到状态代码502：坏网关[已关闭]

Question

在我的项目中将Android Studio更新为最新版本（3.1）和gradle版本后，我收到一个错误（链接总是不同的）：

12:54   Gradle sync started

12:56   Gradle sync failed: Could not HEAD 'https://jcenter.bintray.com/com/android/tools/analytics-library/shared/26.1.0/shared-26.1.0.jar'. Received status code 502 from server: Bad Gateway             Consult IDE log for more details (Help | Show Log) (1m 56s 602ms)

Android Studio版本：

Android Studio 3.1
Build #AI-173.4670197, built on March 22, 2018
JRE: 1.8.0_152-release-1024-b02 amd64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Windows 10 10.0

我已经尝试了清洁重建和更新gradle，重启Android Studio和PC，但没有成功。有什么想法吗？

附言：我当然有互联网。此外，如果您在浏览器中打开链接，文件将被下载。

Answer 1

谢谢大家的快速回答！

“jcenter.bintray.com”网站上似乎出现了暂时的网络问题。我只是多次点击“再试一次”，最后一切都更新了。

此外，如果您在浏览器中打开链接，您将不时收到“服务错误”消息。所以问题不在你这边。

Answer 2

将Android Studio更新为3.1.0后，

我只是遇到了同样的问题，我用

 maven {   url "https://maven.google.com"  }

在项目级gradle中，像这样的顶级BuildScript：-

 buildscript {
    repositories {
      .....
      ...
     maven {   url "https://maven.google.com"   }

参考项目级梯度的样本：-

buildscript {

  repositories {
      google()
      jcenter()
      maven { url 'https://maven.fabric.io/public' }
      maven { url 'https://jitpack.io' }
      mavenCentral()
      maven { url 'https://maven.fabric.io/public' }
      maven {  url "https://maven.google.com"  }
  }
 dependencies {
     classpath 'com.android.tools.build:gradle:3.1.0'
     classpath 'io.fabric.tools:gradle:1.24.4'
   }
}

 allprojects {
   repositories {
      google()
      jcenter()      
   }
 }

task clean(type: Delete) {
    delete rootProject.buildDir
}

注意：-还有一件事：-

在gradle-wrapper.properties中使用这个：-

  distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

而不是4.1-all。邮政编码。

编辑：-如果您想快速解决问题，也可以尝试添加这些-根据Omar的回答：-

 maven { url "http://dl.bintray.com/riteshakya037/maven" }

随着

  maven { url "https://maven.google.com" }
