Well, if anyone cares, I figured out the problem..
The problem was that by specifying <warSourceDirectory>war</...>, I
forced maven to copy all the files from the 'war' directory into the
target directory. That's great and what I want, but it also copied
files in the uncompiled 'szblankweb' module. Since this step happens
after the gwt-compile, some of the compiled JS files were overwritten
by the un-compiled stubs from the 'war' directory.
So, I am not sure if this is the most elegant solution, I did the
following instead of including the entire 'war' directory:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.1-beta-1</version>
<configuration>
<webResources>
<resource>
<directory>war</directory>
<excludes>
<exclude>**/szblankweb/*</exclude>
</excludes>
</resource>
</webResources>
</configuration>
</plugin>
This way, I am including everything from the 'war' directory except
the stuff that's inside of the stubbed out (un-gwt-compiled) gwt
module folder, in my case 'szblankweb'.
Now, everything seems to be working correctly. If anyone sees a
potential problem with this solution or has a more elegant solution,
please let me know.
Thanks,
Yaakov.
