------------------------------
此错误是由于8080端口被占用，
问题确认，Netstat -a -n -o，列出所有端口使用情况，
通过PID找出此端口进程执行的信息，tasklist /svc /FI "PID eq 3016"
-----------------------
改变端口再次执行，
java -jar jenkins.war --httpPort=$HTTP_PORT， 例如java -jar jenkins.war --httpPort=1080
启动成功；
后打开浏览器，输入http:/localhost:1080，即可看到jenkins的页面
