Problem/Bug Please help. I need help figuring out the problem with my code.

I am very new to coding Bukkit plugins, and i need help with this really simple one:
Its supposed to tell the player hello when he types in the command /hello.
Here is the code:
---------------------------------------------------------------------------------------------------------------------

package me.samyounes03.fakejoin;

import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin{

public void onEnable() {
getLogger().info("Plugin successfully enabled");
}

public void onDisable() {
getLogger().info("Plugin Disabled");
}

public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {

if (sender instanceof Player) {
Player player = (Player) sender;
if (cmd.getName().equalsIgnoreCase("hello")) {


player.sendMessage("Hello, " + player.getName() + "!");

return true;


}

return false;

}
return false;
}
}

-----------------------------------------------------------------------------------------------------------------------------------------
When I put it into my plugins folder and run the server, I can't find it in the plugins list, neither in the help, and when i type the command: it tells me "unknown command". Help Please!

 

Does your server say "Plugin successfully enabled" ?
If not : are you sure you have compile your plugin? is it in the plugin folder of your server?

if yes : it's yout plugin.yml file that is not good, but for this I cannot help you, because I don't really understqnd why it works.
Sometime, i can add a commend, and sometime no.

 

@samyounes03 Please post your plugin.yml as well. Also, it is more helpful to use [code=java][/code], [syntax=java][/syntax], or pastebin.com with Java syntax highlighting.

 

It will be a problem with you plugin.yml - post it on here or pastebin so we can see it

 

@samyounes03 Is this problem solved? If so, please mark your thread as solved! See this for more info.

 

Move your plugin.yml file into the src folder
