I have downloaded commandlinetools-win-6200805_latest.zip from https://developer.android.com/studio and tried to run this command:
sdkmanager "platform-tools" "platforms;android-28"
However its giving this error:
Error: Could not find or load main class Testing Caused by: java.lang.ClassNotFoundException: Testing
Please see:

Essentially, due to some error present in the current provided download of Android SDK Tools, commandlinetools-win-6200805_latest.zip, as of time of this writing (April 15th, 2020), one needs to append --sdk_root=%ANDROID_HOME% in front of sdkmanager, like this:
sdkmanager --sdk_root=%ANDROID_HOME% "platform-tools" "platforms;android-28"
That should work.
