Plugin onCommand

My onCommand function is not running therefore neither are my commands.

I have it in my main class and it is overridden.

Heres my code:

Code:

@Override
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        boolean handled = false;
        TLogger.Info("HI!");
        if (sender instanceof Player) {
            Player player = (Player) sender;
            handled = TCommand.IssueCommand(player, cmd, commandLabel, args);
        }
        return handled;
    }

The "HI!" doesn't even show up in the console when I type a command.
The logger works fine because the enabled and disabled messages show in the console.
Is there an event I need to add to the plugin for commands to work?

Please help I have been searching forever for this answer. Looking at other source code, tutorials and such.
