Execute Commands from Plugin?

Is there a way to execute commands from a plugin? As a simple example, the player types in a command for my plugin, and the plugin will, say, use the server's default /kick. So, how can I, say do /kick from the plugin. (I'm not looking for a way to kick someone, but to run a command that is already in place.)

Here's the first thing I wrote and it does exactly what you want:

package me.coldandtired.bookmarker;

import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.util.config.Configuration;
import org.bukkit.command.Command;

import org.bukkit.entity.Player;
 
public class bookmarker extends JavaPlugin
{
Logger log = Logger.getLogger("Minecraft");
Configuration config;
 
 public void onEnable()
{
PluginDescriptionFile pdf = this.getDescription();
String version = pdf.getVersion();
log.info("Bookmarker " + version + " active!");
config = getConfiguration();
}
 
 public void onDisable()
{
log.info("Bookmarker inactive.");
}
 
 public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args)
{
String s = "";
Player player = null;
if (sender instanceof Player)
{
player = (Player) sender;
}
if (cmd.getName().toLowerCase().equals("bm"))
{
switch (args.length)
{
case 0: // /bm - show a list of bookmarks
{
player.sendMessage("");
player.sendMessage(ChatColor.DARK_AQUA + "----- Bookmarks -----");
for (int i = 1; i < 10; i++)
{
String j = Integer.toString(i);
s = config.getString(player.getName() + ".bm" + j);
if (s == null) s = "";
if (s.length() > 0) player.sendMessage(" " + ChatColor.YELLOW + j + " - " + s);
else player.sendMessage(" " + ChatColor.GRAY + j + " -");
}
break;
}
case 1: // /bm x - run a bookmark
{
s =  config .getString(player.getName() +".bm" + args[0]);
if (s != null && s.length() > 0) player.chat(s);
else
if (args[0].matches("^[1-9]"))
{
player.sendMessage("");
player.sendMessage(ChatColor.DARK_RED + "No bookmark assigned to " + args[0] + "!");
player.sendMessage("");
}
else if (args[0].equalsIgnoreCase("help") || args[0].equalsIgnoreCase("?"))
{
player.sendMessage("");
player.sendMessage(ChatColor.DARK_AQUA + "----- Usage -----");
player.sendMessage(ChatColor.GOLD + " /bm " + ChatColor.WHITE + "-" + ChatColor.GREEN + " lists all saved bookmarks.");

player.sendMessage(ChatColor.GOLD + " /bm [1-9] clear " + ChatColor.WHITE + "-"  + ChatColor.GREEN + " clears the selected bookmark.");
player.sendMessage("");
player.sendMessage(ChatColor.DARK_RED + " Add a / to the beginning of a command, otherwise it will be treated as a chat message!");
player.sendMessage("");
}
else
{
player.sendMessage("");
player.sendMessage(ChatColor.DARK_RED + "A bookmark needs to be a number from 1 to 9!");
player.sendMessage("");
}
break;
}
case 2: // /bm x delete
{
if (args[1].equalsIgnoreCase("clear"))
{
s = args[0];
if (s.matches("^[1-9]"))
{
config.setProperty(player.getName() + ".bm" + s, null);
config.save();
player.sendMessage("");
player.sendMessage(ChatColor.DARK_AQUA + "Bookmark " + s + " cleared!");
player.sendMessage("");
}
}
}
default: // /bm x assign command or chat
message
{
if (args[1].equalsIgnoreCase("assign"))
{
s = args[0];
if (s.matches("^[1-9]"))
{
String new_command = "";
for (int k = 2; k < args.length; k++)
{
new_command = new_command + args[k];
if (k != args.length - 1) new_command = new_command + " ";
}
config.setProperty(player.getName() + ".bm" + s, new_command);
config.save();
player.sendMessage("");
player.sendMessage(ChatColor.DARK_AQUA + "'" + new_command + "' assigned to bookmark " + s + "!");
player.sendMessage("");
}
}
}
 		}
return true;
}
return false;
}
}

It also saves each player's favourites. It uses the old config but it's an easy fix.

Feel free to look through it and examine how it works.

 

Shameless self-promotion, lol.
