Java 如何使用我自己的.jar作为api/库？

我正在使用intellij IDEA，并且我已经按照所有指示将我的项目导出为.jar。它说我不能将我的jar用作api并调用这些方法。这是我的罐子：

`package me.JBoss925.com

 import org.bukkit.event.player.PlayerInteractEvent;
 import org.bukkit.event.player.PlayerJoinEvent;
 import org.bukkit.inventory.Inventory;
 import org.bukkit.plugin.java.JavaPlugin;
 import org.bukkit.potion.PotionEffect;
 import org.bukkit.potion.PotionEffectType;

 import java.util.HashMap;
 import java.util.List;
 import java.util.UUID;

             }
         }
     }

         player.addPotionEffect(new PotionEffect(potionEffectType, level, time));
     }

     public static void playerAddUUIDList(Player player, List list){
         UUID i = player.getUniqueId();

要将jar文件添加到项目类路径，请执行以下步骤

Go to Project-> Libraries and add the  folder that has the jars. all in this folder will be added to classpath.

---

这些jar文件将作为api使用。

使用jdk创建包含所有必需类的jar，然后将其包含在类路径中。

---

您应该能够根据需要导入类。

不清楚。你的问题到底是什么？@mskimm我在问如何从这个类中获取方法并在另一个类中使用它们。我将它导出为一个罐子，然后将它添加为一个库，但它不起作用。这不起作用，我也不知道为什么。它不会让我得到方法。如果您的jar文件创建正确，它会工作得很好。按照“如何创建jar”的链接进行操作：
