Flutter environment

Today, when I upgrade flutter, it report some issues for my Android settings, the message is like below:[!] Android toolchain - develop for Android devices (Android SDK version 31.0.0)
   ✗ cmdline-tools component is missing
     Run `path/to/sdkmanager --install "cmdline-tools;latest"`
     See https://developer.android.com/studio/command-line for more details.
   ✗ Android license status unknown.
     Run `flutter doctor --android-licenses` to accept the SDK licenses.
     See https://flutter.dev/docs/get-started/install/macos#android-setup for more details.

For the second problem, just run the command flutter doctor --android-licenses to fix it.

For the first issue, on my environment, I encounter a problem, which is jdk version, because on my computer, I setup jdk 11 as my default version, but when run the command, it always report the following error:Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema

To solve the problem, we need to change the jdk to 1.8.
