Spring Boot app: Not picking up application.properties?

There are various reason for this issue to occur I'm showing what I had come across.

For me it was due to packaging as pom

I had something in my pom.xml as below 

    <packaging>pom</packaging>

So if you have similar thing, then :

 1. Remove it for spring-boot App. 

 2. Delete target folder or mvn clean. 

 3. then mvn install.

 4. Watch your property under target/classes/application.properties file.
