React Native：来自 JCenter 和 Bintray 的 Android“从服务器收到状态代码 502：Bad Gateway”已停止

Question

请注意，这些是我发现有用的错误的 sn-ps，以及以“出了什么问题”开头的 sn-ps。在运行npx react-native run-android --verbose 之后（它一直有效，而且我的 android 开发环境肯定设置正确，因为这个项目昨天工作了）：

然后，我在我的 android 文件夹的 build.gradle 文件中删除了 jcenter() 的实例。我查看了这个答案https://stackoverflow.com/a/70417675/13368695，它说要这样做，以及删除其他两个 URL（我在任何文件中都没有）。结果是这样，下次我跑npx react-native run-android --verbose：

Warning: The 'kotlin-android-extensions' Gradle plugin is deprecated. Please use this migration guide (https://goo.gle/kotlin-android-extensions-deprecation) to start working with View Binding (https://developer.android.com/topic/libraries/view-binding) and the 'kotlin-parcelize' plugin.

> Task :app:checkDebugAarMetadata FAILED

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.

由于这是昨天的工作，这个答案 https://stackoverflow.com/a/35433372/13368695 对我尝试使用代理没有意义，或者这是我的 ISP 阻止网站或互联网连接缓慢的问题。

编辑：我正在寻找一种方法来替换来自 JCenter、Bintray 和其他已经/即将变得不可用的包。

Answer 1

这是 JCenter 的全球性中断。你可以在这里监控状态https://status.gradle.com 它取代了 bintray 状态页面，该页面现在似乎已经完全关闭并返回 502 错误。

更新时间 1 月 13 日 06:35 UTC

JCenter 现已重新上线，系统已全面运行。
