In our projects, we just use our source code path directly.
When launching the project in DevMode from within Eclipse, the launch
config's classpath contains both the "default classpath" plus the /src
directory.
When compiling the project in Ant, we reference the source path
directly in the gwt Compiler call:
<java classname="com.google.gwt.dev.Compiler" fork="true"
maxmemory="512M" failonerror="true" >
<arg line="-war ${temp.war}" />
<arg value="com.x.ModuleName" />
<classpath>
<path location="src" />
<path location="${temp.classes}"/>
</classpath>
</java>
Basically, the GWT Compiler needs both the compiled code and the
source code to successfully compile the module.
Hope that helps.
