所以我对我的yml进行了两次和三次检查，并通过了验证程序。我的插件加载良好，我可以在我的主类中创建一个helloworld命令。但是，在使用第二个.java文件和第二个命令时，它会连续显示我的yml用法文本。
主.java

package lordfluffyjr.TarrenCraft.jEssentialsX.commandSrc;

import java.util.logging.Logger;

import org.bukkit.Bukkit;
import org.bukkit.event.Listener;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin implements Listener { //Extending JavaPlugin so that Bukkit 
knows its the main class

//Housekeeping
Logger jEssentialsXLogger = Bukkit.getLogger();

@Override
public void onEnable(){//  Where plugins will be loaded.
    PluginManager manager = getServer().getPluginManager();
    manager.registerEvents(this, this);
    Bukkit.getServer().getConsoleSender().sendMessage("jEssentialsX has been enabled!");

    //Enable FAQ
    manager.registerEvents(new Faq(), this);
    Bukkit.getServer().getConsoleSender().sendMessage("FAQ has been enabled!");

}

@Override
public void onDisable(){//  Where plugins will be disabled.
    jEssentialsXLogger.info("Test 1 has been disabled!");
    jEssentialsXLogger.severe("Test 1 has an error and has not loaded.");  
    }
}

常见问题.java

package lordfluffyjr.TarrenCraft.jEssentialsX.commandSrc;

import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;

import org.bukkit.event.Listener;

public class Faq implements Listener, CommandExecutor{

public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args)
{
    if (commandLabel.equalsIgnoreCase("faq")) {
        sender.sendMessage("Welcome to our FAQ!");
        return true;
        }
        return false;
    }
}
