I was missing os-maven-plugin jar hence i was unable to resolve my OS to download appropriate jar.
Adding the following dependency fixed the issue

<extensions>
	<extension>
		<groupId>kr.motd.maven</groupId>
		<artifactId>os-maven-plugin</artifactId>
		<version>1.5.0.Final</version>
	</extension>
</extensions>
