  Repository URL: warehouse address
  Credentials: login credentials, configure
  Branches to build from credential management :
  build and
  
  execute shell scripts in the branch
  
  

  #!/bin/bash
  # #!/bin/bash是指此脚本使用/bin/bash来解释执行。其中，#!是一个特殊的表示符，其后，跟着解释此脚本的shell路径。bash只是shell的一种，还有很多其它shell，如：sh,csh,ksh,tcsh,...
  # #!/bin/bash只能放在第一行，如果后面还有#!，那么只能看成是注释。

  #源jar路径，mm打包完成之后，target目录下的jar包名称，也可选择成为war包，war包 可移动到Tomcat的。

  #target打包生成jar包的目录
  
  JAR_PATH=/var/lib/jenkins/workspace/springboot_design_pattern/default/target    # 以具体的打包位置为准，可以先构建一次项目，通过日志查看打包的目录
  
  #打包完成之后，把iar包移动到运行jar包的目录
