plugin.yml:

Code:

Name: Dings2
version: 1.1
main: de.xxibafdasxx.dings.main.Main

commands:
   Scoreboard:
      description: Scoreboard

pl:

Code:

package de.xxibafdasxx.dings.Commands;

import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.scoreboard.DisplaySlot;
import org.bukkit.scoreboard.Objective;
import org.bukkit.scoreboard.Scoreboard;

public class ScoreboardJoinListener implements Listener {

    @EventHandler
    public void handlePlayerJoin(PlayerJoinEvent e) {
        Player p = e.getPlayer();
    
        Scoreboard board = Bukkit.getScoreboardManager().getNewScoreboard();
        Objective obj = board.registerNewObjective("abcd", "abcd");
        obj.setDisplaySlot(DisplaySlot.SIDEBAR);
        obj.setDisplayName("§6Willkommen auf Nexus-server.eu!");
        obj.getScore(" ").setScore(5);
        obj.getScore("Herzlich willkommen" + p.getName() + "!").setScore(4);
        obj.getScore(" ");
        obj.getScore("Viel Spaß!").setScore(3);
    
        p.setScoreboard(board);
    }

}

 

To build on Tim's response, its the name of the command that needs to be lowercase case. Also make sure the the parsing of the plugin.yml is right

Ex.
commands:
<Space><space>scoreboard:

 

Is that correct?


name: Dings2
version: 1.1
main: de.xxibafdasxx.dings.main.Main

commands:
<Space><space>scoreboard:
<Space><space><Space><space>description: scoreboard

 

Any concerns to YML you could use this tool: https://codebeautify.org/yaml-validator

 

@RunsWithShovels There are actually 3 spaces per line but if 2 worked for you thats fine.
@xXDasFabiXx Yes that will work as what with @RunsWithShovels had said but I do recommend having 3 spaces.
