8080 port already taken issue when trying to redeploy project from Spring Tool Suite IDE
<p>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 localhost:8080 </p>

<p>When I change something inside code and try to redeploy it (Run it again - Run As Spring Boot App) I get error message</p>

<blockquote>

<p>If I shutdown process on that port manually everything works fine again, but this can't be right way of redeploying Spring app. Am I doing something wrong here?</p>

<p>I'm using <strong>:: Spring Boot :: (v1.4.1.RELEASE)</strong></p>

<p>P.S. I'm aware that I can setup some kind of hot-swap mechanism to have automatic reload of page after I change code, but for now I would like to resolve this issue first.</p>

<p>Thanks for any kind of help or info.</p>
