Project update does not generate module.gwt.xml with tbroyer mvn plugin

I have a large maven project with lots of modules. Many of them are of type gwt-lib and 2 are gwt-app.
When I try to launch the SDM CodeServer with the eclipse plugin I get errors because the .gwt.xml files are not generated. I need to manually run gwt:generate-module on all the modules before I can start the application properly.
Is this caused by a problem in the pom.xml or is it a problem of the eclipse plugin ?

Start by comparing the Eclipse plugin's project update with manually running gwt:generate-module across the gwt-lib modules, using the pom.xml and generated .gwt.xml files as the evidence. Check whether the issue belongs to the Maven configuration or Eclipse plugin integration; it is done when project update generates the required files and the SDM CodeServer launches without these errors.
