java - maven copy a particular dependency jar to a specific directory in the .war file -

i trying out simple java web start project based on oracle tutorial. using maven package webapp , deploy application server. full source code available here

https://github.com/kiranmohan/dynamic-tree-javaws-sample-project

the maven project structure like

parent   |--lib |--webapp 

the webapp module maven war module. required package lib.jar @ root of webapp.war. not under web-inf/lib.

how achieve in maven?

i found right way use maven-dependency-plugin. since "lib.jar" not used in compile phase of "webapp" module, package time dependency. using maven-dependency-plugin, can copy lib.jar required directory during prepare-package phase. maven-war package include lib.jar in .war package.
