Have you tried deploying it without the maven plugin to make sure it works?

Solved this issue. For somebody who stuck with similar problem
1) If maven repo contain jar and rar with identical artefactID, maven will be download jar. So, rar need to be deployed with another artefactID.
2) Deployable files saved in dir $JBOSS_HOME/standalone/tmp/vfs or $JBOSS_HOME/standalone/tmp/vfs/temp/
