Development Assistance Error in plugin.yml

Hello,
today I decided to start develop my first plugin in Minecraft. I looked for a good tutorial on YouTube and I found this . I wrote perfectly all the code. But when I save the .jar file into my Plugins folder and start the server, on the console appears this message:
[19:04:41 ERROR]: Could not load 'plugins\EightVirtualAdmin.jar'
ins'
org.bukkit.plugin.InvalidDescriptionException: Invalid plugin.yml

I think that the errors appears because in the tutorial says that the name of the package that contains the main of the plugin must be "me.{minecraftusername}.{pluginname}". I didn't put my minecraft username in there because when I tried to do that, an errors appear in the eclipse page: "Invalid package name. '123ottovolante' is not a valid Java identifier". So I wrote "ottovolante321" and not my real username.

The server is hosted on my localhost:25565 and it is a Spigot 1.8

How can I solve this?

Thank you

First off... TheBCBroz was making a suggesting xD the package name can be anything. Mine is usually
"makingplugins.me.{plugin name}". Next thing whats wrong is that your plugin.yml is
me.ottovolante321.MyPlugin.Plugin the last part, .Plugin, is wrong. Your plugin.yml should be...

Code:

name: EightVirtualAdmin
main: me.ottovolante321.MyPlugin.Eight
author: ottovolante321
version: 1.0
description: Mmmhh.. Dat plugin...

commands:
  eight:
     description: Get Info about EightVirtualAdmin

When you make the main: it needs to be {your}.{package}.{name}.[MAIN .JAVA file] (ak.a. me.terturl.com.Main)
also, you forgot to put author in it This should make it work

 

It doesn't work, can you post the code on pastebin?
Now on the console appear:
[20:40:05 ERROR]: Could not load 'plugins\EightVirtualAdmin.jar' in folder 'plugins'
org.bukkit.plugin.InvalidPluginException: Cannot find main class `me.ottovolante
321.EightVirtualAdmin.Eight'

 

@EightCraft Please please please, find better tutorials. The BCBroz has extremely bad practices, and you should not watch his videos. I would recommend @PogoStick29's videos, and you can also learn Java from him, which is important to learn as Bukkit is simply an implementation of Java.​

 

you should have just copied and paste what I put xD
