Using GWT compilation with maven

Hello,

I have a gwt-maven project using Jboss but sometimes the build artifact for GWT doesn't work.
I add the mygwtproject:war exploded to my Jboss deployment, and change it's path to /folder/mygwtproject.war

I build everything with maven, then I clean the gwt  pom project target and I launch the Jboss server with the war:exploded.
The problem is that it only makes the war:exploded so it's missing the gwt compilation folder.
There is no error, it just doesn't do it while the compiler output is present in the artifact configuration.

Anyone has an hint or it's a bug?
