[Maven] How to use War Build Goals

I'm get it on apach main website.

http://maven.apache.org/maven-1.x/plugins/war/goals.html

this is how to make war build. and make goals.

Goal	Description
war	Build a war file. This goal simply executes the war:war goal
war:init	Initialize the file system and attain any necessary goals
war:war	Build a war file.  This goal simply package the directory created by war:webapp goal. Additional custome content which should be included in the archive can be provided using:  <postGoal name="war:webapp">
war:war-resources	Copy files from maven.war.src to maven.war.webapp.dir
war:webapp	Build a webapp directory in that created by war:war-resources, copying libraries, classes and tlds
war:install	Install the war in the local repository
war:install-snapshot	Install the snapshot version of the war in the local repository
war:deploy	Deploy the war to the remote repository(ies)
war:deploy-snapshot	Deploy the snapshot version of the war to the remote repository(ies)
war:clean	Delete all artifacts created by war plugin
war:inplace	Build an exploded web application into ${maven.war.src}. This allows you to mount it in your application server, and you only need to run it again for dependency and class changes, not JSP changes. This goal will not clean old dependencies - due to the dangers involved in automating this for your source tree, you must do that yourself.
