Flutter 无法确定任务 ':app:processDebugResources' 的依赖关系

Question

无法确定任务 ':app:processDebugResources' 的依赖关系。

无法解析配置“:app:debugRuntimeClasspath”的所有任务依赖项。 无法解析 com.facebook.android:facebook-login:[5,6)。

要求： 项目：应用程序 > 无法列出 com.facebook.android:facebook-login 的版本。 > 无法从 https://google.bintray.com/exoplayer/com/facebook/android/facebook-login/maven-metadata.xml 加载 Maven 元数据。 > 无法获取资源“https://google.bintray.com/exoplayer/com/facebook/android/facebook-login/maven-metadata.xml”。 > 无法获取“https://google.bintray.com/exoplayer/com/facebook/android/facebook-login/maven-metadata.xml”。从服务器收到状态码 502：Bad Gateway

• 尝试： 使用 --stack trace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。运行 --scan 以获得完整的见解。

google.bintray.com 下线但 com.facebook.android:facebook-login 版本未严格指定的问题。

这[5,6)表示它的版本范围Gradle Declaring Versions and Ranges

1. 搜索 com.facebook.android:facebook-login Maven search 的版本。我们有 5.15.x

2. 使用最大可能的版本 5.15.3 约束您的传递依赖

编辑您的项目app/build.gradle：

dependencies {
  ...
  constraints {
    implementation('com.facebook.android:facebook-login') {
        version {
            strictly '5.15.3'
        }
    }
  }
}
