Configuring build profiles for Maven to change values in spring-boot properties file

I am following this tutorial so that Maven will replace values in my application.properties file depending on the build profile:

https://www.petrikainulainen.net/programming/tips-and-tricks/creating-profile-specific-configuration-files-with-maven/

  1. It states to put some config files under the "profiles" directory. Where is this directory? I created a folder named "profiles" in the root of the project directory.

  2. How do I activate a profile? I Googled around and I added -P to the commands, for example "mvn test" would be "mvn test -P staging"

Needless to say, it is not working. Even when the default profile "dev" is supposed to be activated without any action necessary, my application.properties file is not affected.

Saying it clearly the tutorial is simply wrong. A spring-boot profile is something different than a maven profile. Having different profiles in spring-boot can be achieved by using application-dev.properties whereas the application.properties is the default. You can have as many as you wish. Those spring boot profiles can be activated via --spring.profiles.active=dev for example. No directories needed etc. - khmarbaise
Please read the documentation of Spring boot about profiles for example springboottutorial.com/spring-boot-profiles and take look at docs.spring.io/spring-boot/docs/current/reference/html - khmarbaise

The tutorial I linked above worked. The only difference is that when using for Spring Boot with the spring-boot-starter-parent

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.1.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>

The format of the placeholder string is

and not

${my.variable}
