Unity 构建 APK 失败。无法解析 com.facebook.android:facebook-applinks

Question

当我构建我的 Unity 项目 APK 时，我收到一个关于 gradle build failed 的错误。挖掘日志我发现这是因为 bintray GET 请求返回 502 错误：

Could not GET 'https://dl.bintray.com/ironsource-mobile/android-sdk/com/facebook/android/facebook-applinks/maven-metadata.xml'. Received status code 502 from server: Bad Gateway

我正在为 Unity 使用 Facebook SDK 11.0.0。 Unity 版本 2019.4.17，构建目标 Android ARM64。在 Preference > External Tools 中，我将 Gradle 设置为 gradle 6.8

有没有办法解决这个问题？

这是完整的错误日志：

CommandInvokationFailure: Gradle build failed. 
D:/UnityEditors/2019.4.17f1/Editor/Data/PlaybackEngines/AndroidPlayer\OpenJDK\bin\java.exe -classpath "D:\Android\gradle-6.8\lib\gradle-launcher-6.8.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "assembleDebug"

看起来您正在尝试下载旧版本的 facebook 适配器（如评论中所述 - bintray 正在关闭） IronSource 最新的集成显示该工件现在是从一个新位置下载的： https://developers.is.com/ironsource-mobile/android/mediation-networks-android/#step-2

替换您当前的集成并按照此处说明的统一集成指南进行操作：https://developers.is.com/ironsource-mobile/unity/mediation-networks-unity/#step-1

它会解决你的冲突。
