How to create a single executable war in spring boot - maven

Question

We are working on spring cloud project using spring boot. Our goal is to create an executable war that can be run using java -jar .
I followed couple of posts on SO and was able to generate the executable war by 1) adding "boot" classifier tag in .
2) Adding Repackage goal in execution phase for spring-boot-maven-plugin
Now with this approach I'm getting two war files :
one war that is not executable but just deployable
and another war with boot classifier that suits my requirements
Is there a way to just generate only the executable war?
I'm attaching the pom.xml for easy reference

Thanks to Stephane for suggesting to remove the classifier and for suggesting to use starter.io.
My original problem was I was getting two war files in the target:
Root.war and the other
discovery-service-boot.war
I guess, the devil was in the maven-war-plugin config. After I removed the xml tags for warName and outputDirectory, I'm getting the executable war.
I'm posting the final pom.xml to benifit others facing similar situation:
