8080 port already taken issue when trying to redeploy project from Spring Tool Suite IDE

It sometimes happen even when we stop running processes in IDE with help of Red button , we continue to get same error.

It was resolved with following steps,

1. Check what processes are running at available ports

netstat -ao |find /i "listening"

We get following

TCP 0.0.0.0:7981 machinename:0 LISTENING 2428 TCP 0.0.0.0:7982 machinename:0 LISTENING 2428 TCP 0.0.0.0:8080 machinename:0 LISTENING 12704 TCP 0.0.0.0:8500 machinename:0 LISTENING 2428

i.e. Port Numbers and what Process Id they are listening to

2. Stop process running at your port number(In this case it is 8080 & Process Id is 12704)

Taskkill /F /IM 12704 (Note: Mention correct Process Id)
