If you have not configured the IDE to create a temporary server automatically, you receive a message that a temporary server will be created. Otherwise, the IDE creates the temporary server without prompting you to confirm.
This creates a temporary server which is configured for your project type of project and searches for the project output files in the output directory specified in the project's properties. This also automatically associates the server with your project and starts it.
Closing the project or the IDE deletes the temporary server.
