Grails Maven plugin

[Marouane Amraoui]

Hi,
I use grails maven plugin.
I have Multi project :

Parent
  -àchild1 (jar)
  -àchild2 (jar)
  -àchild3 (war : grails web application)


I launch mvn clean install on parent pom. So I need to exclude packaging phase 
for project child3 (grails web application) ???
For child3 I don't want to generate war.

Any idea
thx
