为什么 Flutter 构建失败并出现错误 Could not resolve all files for configuration ':app:debugRuntimeClasspath'

Question

我想使用 flutter video_payer api 在我的应用程序中显示来自网络的视频。我升级到最新版本，但现在无法构建我的应用程序。正在显示以下错误-

PBI: {"kind":"error","text":"Invoke-customs are only supported starting with Android O (--min-api 26)","sources":[{}],"tool":"D8"}

AGPBI：{"kind":"error","text":"Invoke-customs are only supported starting with Android O (--min-api 26)","sources":[{}],"tool":"D8"} AGPBI：{"kind":"error","text":"Invoke-customs are only supported starting with Android O (--min-api 26)","sources":[{}],"tool":"D8"} AGPBI：{"kind":"error","text":"Default interface methods are only supported starting with Android N (--min-api 24): void com.google.android.exoplayer2.Player$EventListener.onLoadingChanged(boolean)","sources":[{}],"tool":"D8"} ****************************************************** ******* 警告：如果此版本的 video_player 或其依赖项与 AndroidX 不兼容，它将破坏您的 Android 构建。有关该问题及其解决方法的更多信息，请参阅。对于所有 Android 构建失败都会打印此警告。错误的真正根本原因可能无关。 ****************************************************** ******* AGPBI：{"kind":"error","text":"Default interface methods are only supported starting with Android N (--min-api 24): void com.google.android.exoplayer2.Player$EventListener.onLoadingChanged(boolean)","sources":[{}],"tool":"D8"}

失败：构建失败，出现异常。

出了什么问题：无法解析配置“:app:debug运行timeClasspath”的所有文件。

尝试：运行使用 --stacktrace 选项获取堆栈跟踪。运行使用 --info 或 --debug 选项以获得更多日志输出。运行使用 --scan 以获得完整的见解。

我想不通这个问题。好像是什么问题？

在日志中，它说

The dependency contains Java 8 bytecode. Please enable desugaring by adding the following to build.gradle android { compileOptions { sourceCompatibility 1.8 targetCompatibility 1.8 } }

如果您使用的是 Java 8，请将以下代码添加到您的 android/app/build。gradle

android {
  ...
  // Configure only for each module that uses Java 8
  // language features (either in its source code or
  // through dependencies).
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
}

如果它不起作用，请尝试使用 Java 10（在您的情况下）

android {
      ...
      // Configure only for each module that uses Java 8
      // language features (either in its source code or
      // through dependencies).
      compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_10
        targetCompatibility JavaVersion.VERSION_1_10
      }
    }
