Config comments not generated

I have my plugin config setup so there is a line starting with '#' that describes what each option in the config does.

When I run the server and open the config from the "Server -> Plugins -> <PluginName> - > config" directory, the config only shows the keys and values, but not the comment lines.

Any solutions? Thanks

May I ask how you input these comments? The only viable way I have seen is using Buffers.

 

By putting a # in front of the line of text. I have seen lots of other plugins do it.
Example:

Code:

#This setting does something
settings-1: 'Hello world'

#This settings does something else
setting-2: 'Goodbye world'

 

@ItsMas_
Do you have any code so far?
Like I said BufferedWriters is the only way I've seen it done.
