But there is a way to set the active.profile in the application.properties file while building the application by using maven-profiles.. Let's say there are three environments property files in our application: Maven profiles provide the ability to customize build-time metadata under certain conditions, for example if a specific system property is set.

It provides goals to read properties from files and URLs and write properties to files, and also to set system properties. Just add them as a child element of the project element.
