Spring boot: path to application.properties

Question

Let's say I want to load the application.properties from /tmp/application.properties. How do I do it when I usually execute the app with

mvn spring-boot:run

I read all docs and stackoverflow posts but I cannot get it working. Usually I find:

java -jar -Dspring.config.location=<path-to-file> myBootProject.jar

But this does not seem to work when executing via mvn-spring-boot:run. I also tried without success:

mvn spring-boot:run -Drun.jvmArguments="-Dspring.config.location=/tmp/application.properties"

Answer 1

The spring-boot:run goal has an optional parameter that is used exactly for that purpose: spring-boot.run.arguments.

In your case, the property you want to configure is --spring.config.location=<path-to-file>. So you can use the following command:

mvn spring-boot:run -Dspring-boot.run.arguments=--spring.config.location=<path-to-file>
