Jar does not contain plugin.yml

I have the following code below.

I am creating a plugin for Minecraft using the Spigot/Bukkit API and the java programming language.

I have created this using the maven tool on eclipse.

I enter mvn clean package into the terminal on my mac to compile the '.jar' file.

I then drag this '.jar' file into my 'plugins' folder on my server.

However, I keep getting the issue: java.io.FileNotFoundException: Jar does not contain plugin.yml

I am not sure why the jar file does not contain the plugin.yml.

I would be so grateful for a helping hand!

pom.xml file:

Code:

plugin.yml file:

Code:

name:newestplugin
main:newestfile.here.newestplugin.Main
version:0.0.1-SNAPSHOT
api-version: 1.19 

The top few lines of my '.java' file:

Code:

package newestfile.here.newestplugin;

import java.util.UUID;
import java.nio.charset.StandardCharsets;
import java.nio.file.StandardOpenOption;
import java.text.SimpleDateFormat;

import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scheduler.BukkitTask;
import java.nio.file.Files;

public class Main extends JavaPlugin implements Listener
{
    boolean stopRepeater;

 

It is not letting me open it for some reason...

 

This is the output when trying with Zip editor:

sorry for the second message - I couldn't add the screenshot to the first!

 

you plugin.yml is pointing to:

you would need to change that to main:Main

 

Sadly still not working really can't understand why!

I now have the error message:

org.bukkit.plugin.InvalidDescriptionException: Plugin description file is empty or not properly structured. Is name:newestplugin main:Main version:0.0.1-SNAPSHOT api-version:1.19but should be a map.

Is the version correct? 0.0.1-snapshot?

 

your plugin.yml should be in the jar at the top
in you plugin.yml you need to write where the main class is.

in the picture i created a simple plugin
my main class is in the "root" directory
and in the plugin.yml i wrote "Main"
because the plugin.yml and main class are in the same directory
if my main would be in "me/dev"
i would write me.dev.Main

make you create an screenshot from you ide it could help

 

Thank you so much for the advice. I changed the newestfile.here.newestplugin.Main and it now does not give any errors

However, I still cannot find the plugin output file?

[Server thread/INFO]: [newestplugin] Loading newestplugin v0.0.1-SNAPSHOT

 

name: newestplugin
main: newestfile.here.newestplugin.Main
version: 0.0.1-SNAPSHOT
api-version: 1.19

I no longer get any errors on the log file

ahhhh - it's finally working!! I can now see the file being generated.

As an example:

Thank you so so so much for all your support.

And apologies if at times I came across as 'stupid' - just to give a bit of context, I am a first-year PhD student in Cognitive Neuroscience. This is my first time learning java and using bukkit/spigot/minecraft
