### 打包流程 ###

**1. 打开菜单栏File-Project Structure**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70][]

**2. 点击Artifacts**

**3. 点击 "+" - JAR - From module with depenencies**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70 2][]

**4. 后弹出如下界面，自此开始，各种问题就来了**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70 3][]

*  首先Module中，我SocketDemo的Module含有SocketDemo、SocketDemo\_main、SocketDemo\_test三个，**一定要选择main**

**        **![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70 4][]

*  Main Class选择自己要打包的类(一个Module一个包下可能有多个类需要打包)，我做了一个测试类Test

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70 5][]

*  JAR files from libraries 第一个选项只生成主类(main)的jar包，第二个选项不太清楚，看别的博客说是生成的jar包包含Module中引用的所有jar包，**但选择第二个很大可能在以后的运行中出现问题**，我反正是选的第一个

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70 6][]

*  接下来是 MF文件的存放目录，**重点**。不能使用默认目录，必须自定义目录，不然会运行错误，也**不能使用src/main/resources这个目录**(这个目录是我建project时自带的，也可能没有)，自定义目录也不能在src/main下建名为resources的文件。于是我新建了resource

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70 7][]

*  最终是这样的，点击OK

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70 8][]

*  **此时应该也必须有META-INF此文件**，不然会运行错误。若JAR files from libraries选择src/main/resources目录，是没有META-INF文件的。Output directory是jar包的保存目录

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70 9][]

*  点击OK

**5. 点击Build-Artifacts**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70 10][]

**6. 点击Build**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70 11][]

**7. 此时Output directory便出现了jar包**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjA4OTE3NQ_size_16_color_FFFFFF_t_70 12][]

**8. 打开CMD窗口，运行jar包。一定要cd到jar包所在目录(Output directory)，****一定要使用java - jar jar包名称**

**结束。欢迎一起交流~~~**
