[Solved]Vaadin + Grails Compilation problem

Hy All of you,

I’m working with vaadin and grails. I succeed to develop what I need. I also run the app either in “production” environments or in “development” one with success.
I can compile the project in “development” environment, unfortunately, I
didn’t succeed in compiling the project in production.

There is no error, the compilation only stops!

Iff anyone could help I’d appreciate.
