It is my first time when I configure a spring boot application from scratch and for 2 days I was having a nightmare with this issue. When I am trying to start the application it looks like it's trying to start twice and every time I got an error that port is already in use, but the process is not stopped and if I'm trying to call an endpoint with postman, it works.
Here is he console output:

Description:
Web server failed to start. Port 8187 was already in use.
Action:
Identify and stop the process that's listening on port 8187 or configure this application to listen on another port.

Here is the build.gradle file for development profile:

And the main class:

log.error("You have misconfigured your application! " +

}
}
}
}
My thoughts are that there is a problem with my build files, but couldn't find a solution yet. Does anyone ever faced the same problem ? Any idea for a solution ? Thanks in advance.
You are invoking SpringApplication::run static method twice.
Firstly using SpringApplication.run(VcrawlPortalBackendApplication.class, args); and them from your initialized SpringApplication instance Environment env = app.run(args).getEnvironment();
