Solved plugin.yml main reference help

Garfield100 · Oct 3, 2015

So I made a test plugin that will just whisper something to the player when he/she types /test.
The only problem I have is that when I try to load the plugin into the server, I get this:
Code:
[19:49:20] [Server thread/ERROR]: Could not load 'plugins/BukkitPlayerTimer.jar' in folder 'plugins'
org.bukkit.plugin.InvalidDescriptionException: Invalid plugin.yml
Now as far as I know, I messed up the "main:" part of the plugin.yml.
The project is called BukkitPlayerTimer, the package is called com.Garfield100 and the class is called Main.java.
The plugin.yml is located in the main project folder. These are its contents:
Code:
name: BukkitPlayerTimer
version: 1.0
author: Garfield100
main: com.Garfield100.Main
commands:
    test:
        description: Just a test
Now, as far as I know I only Need "name:", "version:" and "main:" , although I might be wrong. Anyways, the way I understood the "main:" thing is package name+class name that extends JavaPlugin.

Please help, as this looks like something very easy to solve, which just makes it that much more frustrating.

Regards,
Garfield100

P.S.: If you need the source code or something else, just ask, I'll attatch it.

@Garfield100 Could you post the whole error? The things that come behind "Invalid plugin.yml" specify the error more detailed.

SuperSniper · Oct 3, 2015

@Garfield100 Show us your Main class please, so we can see the Main class name, and the package name. "Invalid plugin.yml" errors are mostly from the "main:" being incorrect, but it's also possible that other things are causing it from the plugin.yml.

@Garfield100 Change your package name, you don't own the domain garfield100.com (I checked, it doesn't exist). Instead, use something such as your email address, github subdomain, or me.(yourname).(projectname)

Thanks, I tried that before, then changed to com since I saw that in many videos. None of them worked. Just to be sure I retried right now, still no success though

Here's a snapshot after I changed com to me (Still doesn't work)
If you also want the Main class source code, just ask!

Have you made sure to refresh your project? Right-click "BukkitPlayerTimer" folder and click refresh THEN export it after.

Just tried that. The problem persists :/
Still, thank you, it's probably a good habit to have!

A) I doubt that it would be an issue in the actual code, but it is possible. Could you provide it?
B) Just for future reference, please follow Java Naming Conventions. Package names should be all lowercase (also be sure to include a unique identifier within your package, such as the project name), and it's best not to use "Main" as the name of your main class (use something like the name of the project).

                Bukkit.dispatchCommand(Bukkit.getConsoleSender(), test);

        }
        return false;
    }
  
}
For B)

Thank you for pointing that out! I adjusted everything, now it looks like this:

The plugin is just supposed to whisper a message to the player that executed it and then "sendMessage" another one to him. Later on it's supposed to time the players time on the server and warn him after 30 mins on week days and after 1h on weekends, with a few more details here and there.

Also, is it normal that next to "+Quote" and "Reply" it sais "Tahg User" instead of "Tag User"?
If it is, why so?

Ok, so a couple of adjustments can be made to your Main class.
A) onEnable, onDisable, and onCommand can all be overridden
B) There is no reason to log when the plugin is enabled and disabled, Bukkit already does this
C) Due to part B, you don't need an onEnable or onDisable
D) In your onCommand, you are checking if the sender is a player before casting, and that is good. However, what will you do if the sender is the console? You check it but you don't handle it
E) Returning false in your onCommand says that it wasn't handled and will display the usage from your plugin.yml
F) When does the error you provided appear? On server startup or when the player runs the command?

Garfield100 · Oct 4, 2015

A) What do you mean "can be overridden"?
B/C) OK, Removed those
D) I have no idea, I just took most of this from a video, so I don't know how to do that. Would that be sender instanceof Console?
E) Ok, returned true;
F) Just checked, it occurs on server startup. I checked the logs without even joining the server.
Here is the error after the adjustments, just in case something changed:

Make sure you're not using any tabs, use spacebar for indenting!

A) What do you mean "can be overridden"?
B/C) OK, Removed those
D) I have no idea, I just took most of this from a video, so I don't know how to do that. Would that be sender instanceof Console?
E) Ok, returned true;
F) Just checked, it occurs on server startup. I checked the logs without even joining the server.
Here is the error after the adjustments, just in case something changed:

You can do

Code:

@Override
public void onEnable() {
}
@Override
public void onDisable() {
}
@Override
public boolean onCommand(parameters) {
}

And you are sure that you never used the tab key in your plugin.yml?

I Al Istannen · Oct 4, 2015

@Garfield100 You definitly used a tab in the plugin.yml. You should remove every intendation and make sure, you use just 2 spaces. If you do that, the error message should go away or change. On the screenshots, it looks like you used tabs infront of "test" and "description".

It doesn't have to be 2 spaces. I use 4 and it works just fine.

I use three spaces for indentation as long as it's consistent then it doesn't matter.

Ok guys, I did what you told me and theres both good and bad news. The bad news is, it still doesn't work.
The good news is, the error changed! (I suppose that's good?

)

As you can see, it now sais "commands are of wrong type".
I have the feeling we're almost there!

P.S.: You made my whole week.

FAZIT:

-DO NOT use tabs to indent the plugin.yml
-MAKE REALLY SURE the package name and the class name are the same as in the plugin.yml
