Server not registering my plugin.yml

I am new to plugin development and ive had a problem in a plugin I want to test were the server says that the plugin.yml is not registering in the server. The logs look like this:

Code:

The layout of my plugin is like this :

Code:

src:
       me.peacemango.Citadel:
                 Main
       me.peacemango.Citadel.KitSelect:
                  Commmands
                 Utils
                 KitSelectUI
       plugin.yml

And my plugin.yml is like this:

Code:

name: Citadel
main: me.peacemango.Citadel.Main
description: Adventure map/plugin
version: 1.0
author: peacemango

commands:
  Chooseclass:

I know it says in the logs that there is no plugin.yml in the plugin but I have triple checked that its in the src and that I have exported with everything selected. I don't know if there is something wrong with the layout of the plugin or the plugin.yml but I am in need of asistance .

Sorry its a little hard to tell were my plugin.yml is in my plugin, it is in my src and not in me.peacemango.Citadel.KitSelect
