No and no. I’m following the structure generated by net.ltgt.gwt.maven’s 

mvn archetype:generate \
   -DarchetypeGroupId=net.ltgt.gwt.archetypes \
   -DarchetypeVersion=LATEST \
   -DarchetypeArtifactId=modular-webapp

That generates Maven’s client, shared and server modules. shared is not a GWT 
module in that structure. At any rate, I changed the module name to have the 
package name set as a super package of both client and shared and the 
compilation goes through. 

Now, while it compiles, the client module tests fail with to instantiate any 
custom widgets that are *below* the module package ‘com.effectiveem.app.gwt’. 
For example, 'com.effectiveem.app.gwt
.client'

[ERROR] 
testUpdateRowWithUnmodified(com.effectiveem.app.gwt.client.document.GapAnalysisItemListTableGWTTest)
  Time elapsed: 0.032 s  <<< ERROR!
com.google.gwt.core.shared.SerializableThrowable: 
com.effectiveem.app.gwt.EemApp.JUnit:com.effectiveem.app.gwt.client.document.GapAnalysisItemListTableGWTTest.testUpdateRowWithUnmodified:
 could not instantiate the requested class
Caused by: com.google.gwt.core.shared.SerializableThrowable: (TypeError) : 
Cannot call method "new" of undefined

Obviously, I’m doing something wrong but I’m struggling to understand what.
