title: Maven plugins in WebApp and deploying
body: <p>I'm using Maven in a JavaEE project. I splited my project into some modules : webapp (view+controler), business, persistence, model.</p>
  
  <p>I'm asking : </p>
  
  <p>--> Do I have to put my maven plugins glassfish into the pom.xml of the web app only or put it into the parent project pom.xml ? 
  I don't understand properly how it works in this case because I have several moduls.</p>
  
  <p>Also, how to deploy it ? I used <code>mvn package glassfish:deploy</code> But come with it the question about where do I have to make it : only in the webapp or in the parent project ? </p>
  
  <p>Thanks for helping me</p>
