Always the dependency issue … the same with your “mvn help:effective-pom"
 
I thing the problem I have is :
-       pouet.product has a dependency on my pouet.product.feature (without this dependency no launcher icons, no update site… the product doen’t have my branding)
-       pouet.product.feature has a dependency on my pouet.product (of course because the feature references the plugin which contains the product)
-       the parent Pom calls the two modules
  <modules>
       <module>../fr.ac6.mcu.product</module>
       <module>../fr.ac6.mcu.product.feature</module>
  </modules>
 
With the Eclipse Product export wizard mechanism no problem, the product is well generated.
 
With Maven : 
[ERROR] Cannot resolve project dependencies:
[ERROR]   Software being installed: pouet.product.feature.feature.group 1.6.0.qualifier
[ERROR]   Missing requirement: pouet.product.feature.feature.group 1.6.0.qualifier requires pouet.product 0.0.0' but it could not be found
[ERROR]
 
It’s not a problem of version (pouet.product 0.0.0 => I’ve tried with 1.6.0 with 1.6.0.qualifier…).
I thing Maven doesn’t manager the cross dependency …
 
Any idea?

I don’t’ understand why I have to add the declaration of tycho extension whereas I’ve it in the parent pom.
try "mvn help:effective-pom" to check whether your pom correctly inherit the content from the right parent.
