Question

编码时出现此语法错误，如果有人知道发布评论，我似乎无法找到问题的根源，谢谢。

问题已经发生了大约2个小时了。我在互联网上搜索了很多来源，这对于那些不熟悉编码的人来说似乎是一个众所周知的问题。

Answer 1

为org.bukkit.plugin.java.JavaPlugin;添加导入声明，将其更改为

import org.bukkit.plugin.java.JavaPlugin;

并在末尾添加}以完成课程。

你的代码中有几个错误，你多次写ChatColor.GOLD + "[StaffViewer]" + ChatColor.AQUA，所以我为它做了一个前缀变量。你的最终代码是：

package me.carwyn123;

import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;

public class Staffviewer extends JavaPlugin {
    String prefix=ChatColor.GOLD + "[StaffViewer]" + ChatColor.AQUA;
    @Override
    public void onEnable() {
        getLogger().info("Staffviewer plugin now enabled / plugin made by carwyn123");
        getConfig().options().copyDefaults(true);
        saveConfig();
    }

    @Override
    public void onDisable() {
        getLogger().info("Staffviewer as been disabled / plugin made by carwyn123");
        saveConfig();
    }

    public boolean onCommand(CommandSender sender, Command cmd, String Label, String[] args) {

        // the staff list code

        if (cmd.getName().equalsIgnoreCase("staff") && sender instanceof Player) {
            if ( !sender.hasPermission("staffviewer.staff")) {
                sender.sendMessage(prefix + "You don't have permission");
                return true;
            }

            Player player = (Player) sender;

            player.sendMessage(ChatColor.AQUA + "================================");
            player.sendMessage(ChatColor.GOLD + "        Staff members");
            player.sendMessage(ChatColor.AQUA + "================================");
            player.sendMessage(ChatColor.GREEN + getConfig().getString("staffmembers"));
            player.sendMessage(ChatColor.AQUA + "================================");
            player.sendMessage(ChatColor.AQUA +  getConfig().getString("staffmembers"));
            return true;

        }


        // staff help code
        if (cmd.getName().equalsIgnoreCase("staffhelp") && sender instanceof Player) {
            if ( !sender.hasPermission("staffviewer.help")) {

            }

            Player player = (Player) sender;

            player.sendMessage(prefix + "Here is the list    of commands" );

            player.sendMessage(prefix + "/staffadd: adds staff to the list, using config allows for more design");
            player.sendMessage(prefix + "/staffhelp: gets you to this page");
