Spring Tool Suite - Port 8080 required by Pivotal tc Server Developer Edition v3.0 is already in use

You have a application running on 8080, so you need to terminate whatever is running currently on 8080 port.

If you running Windows use:

netstat -a -o | find "8080"

If you running Mac OS (which i think you are) use:

sudo lsof -i :8080

Terminate that application and then launch Pivotal.

Otherwise you can change pivotal server port in the config file:

<your tc server folder location>/conf/catalina.properties

Hope that helps.

steps to be followed

• change the port number in catalina.properties file under server folder

  e.g.
  bio.http.port=18080
  bio.https.port=18844

• kill the java.exe running on port 8080(or any other port which poses the issue)-
  Use TcpView to kill the process on specfic port
• Right click on the server and then click on "clean tc server work directory"
• Right click on the server and then click on "Clean"
• and there u go "baaaam"
