Flutter 医生 --android-licenses 不工作

Question

I have installed flutter 2 on a windows laptop. When I run flutter doctor it works fine but I understand that we have to accept licenses by flutter doctor --android-licenses . When I run this command I found below error

flutter doctor --android-licenses
Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema
        at com.android.repository.api.SchemaModule$SchemaModuleVersion.<init>(SchemaModule.java:156)

I don't know about this error and how to solve this?

Installing Android SDK Command-line tools from Android SDK Manager did the job.
