java - 找不到符号枚举

问题描述

我正在使用 javac 手动编译 Java 代码，但出现以下错误：

Packet.java:13: error: cannot find symbol
    public final PacketType type;
                 ^
  symbol:   class PacketType
  location: class Packet
Packet.java:22: error: cannot find symbol
            type = PacketType.UNDEF;
                   ^
  symbol:   variable PacketType
  location: class Packet
Packet.java:26: error: cannot find symbol
        type = PacketType.values()[message[0]];
               ^
  symbol:   variable PacketType
  location: class Packet
3 errors

包.java：

  package gameManager.gameServer;

  import java.util.logging.Logger;

  public class Packet {

    private static final Logger LOGGER = Logger.getLogger(Class.class.getSimpleName());

    public static final int PACKET_SIZE = 1024; //Packet size in bytes



    public final PacketType type;
    public final byte[] data = new byte[PACKET_SIZE-1]; //Data size is PacketSize minus PacketType Header




    public Packet(byte[] message) {
        if(message.length != PACKET_SIZE) {
            LOGGER.warning("Tried to create a packet with insufficent amount of data");
            type = PacketType.UNDEF;
            return;
        }

        type = PacketType.values()[message[0]];

        for(int i = 0; i < data.length; i++) {
            data[i] = message[i+1];
        }
    }




  }

PacketType.java：

package gameManager.gameServer;

public enum PacketType {

    UNDEF, JOIN_SERVER, MOVE, SHOOT, CHANGE_INVENTORY;

}

我正在使用编译 javac PacketType.java && javac Packet.java

我不知道为什么这不会编译，我已经编译了 PacketType.java 并且 Eclipse 从 Packet 中看到 PacketType 没有问题

解决方案

将目录更改为src，尝试以下命令：

javac -cp src ./src/gameManager/gameServer/Packet.java
