[!] Gradle threw an error while downloading artifacts from the network. Retrying to download...

我正在使用 Mac OS、flutter 和 android studio。我可以在没有任何此类错误的情况下构建 iOS 应用程序。我该如何解决这个问题？

我试过这个，

Go to flutter_app => android => gradle => wrapper directory
Delete gradle-wrapper.jar file
Open and edit gradle-wrapper.properties file
Change distributionUrl=https://services.gradle.org/distributions/gradle-x.x.x-all.zip to gradle-7.2-all.zip or latest
On terminal use flutter run command

但我仍然遇到同样的错误。

这是我的 android/build.gradle 文件：

【问题讨论】：

标签： android flutter android-studio gradle

【解决方案1】：

正如堆栈跟踪中所说，尝试从 url https://google.bintray.com/ 下载依赖项，但得到 502 http error。如果您在浏览器上测试此链接，您也会收到此错误。请参阅此 link 这可能是存储库中的临时错误。

您还可以将 build.gradle 中 repository 闭包中的所有 jcenter() 替换为 mavenCentral()。同步 Gradle 并重新构建。

【讨论】：

它已经有 mavenCentral()
@Shashiwadana 你能发布你的 build.gradle 吗？（我的意思是根和应用模块.gradle）。据我所知，如果您已将所有存储库设置为 maven Central，它将不会尝试从此链接下载。
我添加了根 build.gradle 文件
@Shashiwadana 你有all projects{ .... maven {url 'https://google.bintray.com/exoplayer'} } 并且你可以尝试解决一个不在mavenCentral 中的exoplayer 依赖项，所以Gradle 将此存储库传递给google bintray 并且google.binray.com 暂时关闭。检查此链接(stackoverflow.com/questions/69318147/…) 并尝试在mavenCentral 中找到合适的 exoplayer 版本或等待 google bintray 中的问题得到解决。
