How to use ember deployed jar

I have a spring mvc web project & an ember-cli project. I have used ember deploy to generate the maven jar. As required, all contents of the dist folder are copied into the jar.

I have supplied the dependency of this jar to my spring project and it is on the classpath. How can I ensure that all the contents of this jar are copied as a part of webResources?

I tried using maven-war-plugin but the webResources tag expects a directory to be specified. I am unaware of the syntax required to specify the jar as a directory of resource there.

P.S. : I am using Java 7, ember cli 1.13
