Including into <project>.gwt.xml breaks it

[Talsman]

Hi, I'm trying to incorporate gwt-log into my application but it seems
that just trying to add the import causes it to explode. I'm running
GWT 2.0 and trying to use GWT Log 3.0.0. The application utilizes
other GWT asynchronous functionality already without difficulty until
the gwt-log inheritance line is added to the module file
(VTD2.gwt.xml) as so:

----
<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='vtd2'>
<!-- Inherit the core Web Toolkit stuff. -->
<inherits name='com.google.gwt.user.User'/>

<inherits name='com.google.gwt.user.theme.standard.Standard'/>

<!-- Other module inherits -->
<!-- GWT Logger. Levels: (TRACE, DEBUG, INFO, WARN, ERROR, FATAL,
OFF) -->
<inherits name='com.allen_sauer.gwt.log.gwt-log-DEBUG'/>

<!-- Specify the app entry point class. -->
<entry-point class='tmst.vtd2.client.VTD2'/>

<!-- Specify the paths for translatable code -->
<source path='client'/>
</module>
----

Upon trying to execute the web application in eclipse, it gives the
following error to the console:

Loading modules
tmst.vtd2.VTD2
Loading inherited module 'com.allen_sauer.gwt.log.gwt-log'
Loading inherited module 'com.allen_sauer.gwt.log.gwt-log-

I've been looking all over for what might cause this behavior. Any
ideas? Any help would be greatly appreciated.

Thanks in advance.

Talsman,

I haven't seen this one before. Do you have all the GWT jars in the classpath?

In particular look for this class:

  com/google/gwt/core/ext/Generator
