Spring Boot overriding YML profile from Command Line - spring

Question

I wan't to override an existing YML file profile using command line, so I did this.
Created a folder and added to the classpath
Copied another application.yml in that new folder
Ran this command mvn spring-boot:run -Dspring.profiles.active=unit-test
but it still picking up the "default" active profile from the source code application.yml. I also tried creating a application.properties instead of application.yml but it still didn't get picked up?
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
#Configuration
#EnableAutoConfiguration
#ComponentScan
public class SuchApplication implements CommandLineRunner {
#Autowired
private DogeService dogeService;
#Override
public void run(String... args) {
System.out.println("AutoConfiguration should have wired up our stuff");
System.out.println("Let's see if we are doge-worthy...");
if (dogeService.requiresDogeness()) {
System.out.println(dogeService.leDoge());
} else {
System.out.println("No Doge for us :(");
}
}
public static void main(String[] args) throws Exception {
SpringApplication.run(SuchApplication.class, args);
}
}
I have the following YML file under my resources folder
spring:
profiles.active: default
---
spring:
profiles: default
doge:
wow: 10
such: so
very: true
---
spring:
profiles: unit-test
doge:
wow: 4
such: so
very: true

I had a similar problem with Spring Boot and resolved it with this annotation in my configuration class...
#PropertySource("classpath:application.yml")
But from the official Spring documentation, this annotation looks unnecessary, which is why I did not add on the first attempt.
