需要配置端口号和jar包名称，如下为8080和web.jar
    自动获取当前路径，jar包放在同脚本目录下的版本目录（eg：1.0.0）中，
    自动使用kill-15自动杀死对应端口的进程，5秒后未杀死可以使用kill-9强制杀死进程，
    最后选择性输出启动日志。
    脚本如下：

    1. #!/bin/bash
    3. # 读取端口号
    4. port=8080
    5. baseDir=$(pwd)
    6. dir=$1
    7. project="web.jar"
    9. # 确认端口号
    10. echo "[  warn] Is the port($port) right? [Y/N]"
    11. read isPortOk
    12. if [ "$isPortOk" != "Y" ]; then
    13.   echo '[  info] exit.'
    14.   exit 0;
