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

Question

I have strange thing when I try to modify Spring project inside my Spring Tool Suite. On the first load (deploy) everything is fine, application compiles and runs on localho

Answer 1

Am I doing something wrong here?

Yes, you are. One servlet container is already running on port 8080 and you are trying to run another one on port 8080 again.

Either restart the server (If there is button for that in STS) or stop and start it
