当我使用android studio导入项目时,我遇到了一个问题.更多细节如下:```

Error:Execution failed for task ':app:transformClassesWithDexForArmDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_161.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1
```

And the Gradle console show the following message:

---------

当我第一次下载 11.4 beta 版本的 Xcode 时，我可以在模拟器和 flutter 项目的设备上运行应用程序。但是，当我验证和上传我的应用程序时遇到了问题：

App Store 连接操作错误

无效的工具链。您的应用程序是使用不受支持的 SDK 或 Xcode 版本构建的。如果您计划将此版本提交到 App Store，请确保您使用的是https://help.apple.com/xcode/mac/current/#/devf16aefe3b或更高版本中列出的版本。

我怎样才能解决这个问题？
