"Cannot resolve constructor"我需要帮助知道程序出错的地方

Question

我正在尝试更新这个Spigot插件，但在处理聊天的部分收到了一个错误。我已经更新了API，相同的代码部分适用于以前的版本，所以我猜需要一些新的东西，但我不知道是什么。

相关库为craftbukkit-1.16.3-R0.1-SNAPSHOT

无法解析构造函数"PacketPlayOutChat(net.minecraft.server.v1_16_R2.IChatMutableComponent(">

这是Intellij:中引发错误的特殊代码段

public void sendJson(Player p) {
((CraftPlayer) p).getHandle().playerConnection.sendPacket(new PacketPlayOutChat(ChatSerializer.a(toString())));
}

这是java类的其余部分，以防其中的某些内容与问题有关。

}
private void addSegment(String segment) {
String lastText = extras.get(extras.size() - 1);
lastText = lastText.substring(0, lastText.length() - 1) + "," + segment + "}";
extras.remove(extras.size() - 1);
extras.add(lastText);
}
public String toString() {
if (extras.size() <= 1)
return extras.size() == 0 ? "{text:""}" : extras.get(0);
String text = extras.get(0).substring(0, extras.get(0).length() - 1) + ",extra:[";
extras.remove(0);
;
for (String extra : extras)
text = text + extra + ",";
text = text.substring(0, text.length() - 1) + "]}";
return text;
}
public void sendJson(Player p) {
((CraftPlayer) p).getHandle().playerConnection.sendPacket(new PacketPlayOutChat(ChatSerializer.a(toString())));
}
public void sendAllJson() {
for (Player p : Bukkit.getOnlinePlayers())
sendJson(p);
}
}

我对java还不太了解，很抱歉，如果我的问题很模糊，

PacketPlayOutChat构造函数不排除ChatSerializer.a()返回的对象。它正在排除一个IChatMutableComponent对象。
