Technical (fail) difficulties..

Hi everyone, I am trying to learn how to start around with this fancy java coding.
I seem to be stuck with an error that it cannot load my plug-in from the plug-ins folder.
" [SEVERE] Could not load 'plugins\MineOS.jar' in folder 'plugins\' "'


I was relatively bored and just wanted to make a simple message dispensing command, which in this case is /reboot.

I've got a scrap class and plugin.yml here

Code:

package me.Lildirt.Learning2;

import java.util.logging.Logger;

import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.plugin.java.JavaPlugin;

public class Learning2 extends JavaPlugin {

    Logger log = Logger.getLogger("Minecraft");

    public void onEnable(){
        log.info("Booting MineOS..");
    }

    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
        if(cmd.getName().equalsIgnoreCase("reboot")){ // If the player typed /reboot then do the following...
            sender.sendMessage("MineOS is rebooting!");
            return true;
        } //If this has happened the function will break and return true. if this hasn't happened the a value of false will be returned.
        return false;
    }



    public void onDisable(){
        log.info("MineOS is shutting down..");
    }
}

And my plugin.yml

Code:

name: MineOS
main: me.Lildirt.Learning2
version: 0.01
commands:
    reboot:
        description: Gives back a message, because it can.
        usage: /command

From what I can understand, this error is from my .yml
But, I don't understand how, or why for that matter?

EDIT: Do please note all of this is what I learned from the Bukkit wiki. I cannot assure that this coding is remotely close to what it should be.
EDIT2: I get "JAR creation failed. See details for additional information.
Resource is out of sync with the file system: '/MineOS/plugin.yml'.
" on Eclipse when trying to export my jar..

 

I'm sure there are more lines after this, one of them telling that the class "me.Lildirt.Learning2" cannot be found. Which is because me.Lildirt.Learning2 is the package, the class is me.Lildirt.Learning2.Learning2 ! So your plugin.yml has to look like this:

Code:

name: MineOS
main: me.Lildirt.Learning2.Learning2
version: 0.01
commands:
    reboot:
        description: Gives back a message, because it can.
        usage: /command

Click on the yml in eclipse file list (left side) and press F5.
If you're using linux mount the filesystem the workspace is on with the noatime option.

And next time post the full error, not only the first line.

 

Oi.. I'm not going to get far on coding .. *brain throb*

Okay then, all problems fixed. It was just me not refreshing the YML..
I'm going to go hide in a corner now ._.

This works fine on WinVista 32-bit, but not a win7 64-bit.
Nice. FML.

What exactly is "this"?

 

The most simple plug-in that I've ever seen.
Just a plugin that you do a /command, and it returns a line of text.
