Hi,

I am trying to get a very simple GWT project to gwt-compile using the
codehaus' maven-gwt plugin but I don't seem to be having much
success...

The project is nothing more than a regular starter GWT 1.7 (same as
1.6 plus bug fixes) Eclipse GWT plugin project. All I did after
creating a new project in Eclipse with the GWT Eclipse plugin was to
create main/java under the src directory and put that into the class
path instead of just the default src directory.

My pom.xml is shown below. When I do 'mvn clean compile', I see that
GWT compile gets kicked off, but when I go the exploded built WAR and
double click on the host HTML page, it tells me "GWT module
'szblankweb' needs to be (re)compiled, please run a compile or use the
Compile/Browse button in hosted mode". Same thing happens if I deploy
the .war file into a container.

If I run the app inside Eclipse in hosted mode and then do 'mvn
package' (without the clean), everything works.

Any idea of what I am not doing or doing wrong here?

Here is my pom.xml:
