Amine :

You can try this solution

First open sdkmanager.bat with any text editor

Then find this line

  %JAVA_EXE%" %DEFAULT_JVM_OPTS% %JAVA_OPTS% %SDKMANAGER_OPTS%

And change it to this line

  %JAVA_EXE%" %DEFAULT_JVM_OPTS% --add-modules java.xml.bind %JAVA_OPTS% %SDKMANAGER_OPTS%

I hope this solves your problem.
