Just a follow-up -- in case anyone else here ever encounters this issue. I found the root cause.
Running mvn clean gwt:compile fails for me because I now have order- dependency in the build. mvn clean wipes out the classes/* directory gwt:compile then tries to compile the GWT code, but needs classes b/c it tries to resolve the class specified by the @GinModules annotation. I discovered this via a total fluke. I changed some whitespace in the Eclipse IDE and saved, and lo and behold gwt:compile worked from cmd line. I cleaned everything and tried gwt:compile again and it failed. Eclipse auto-build creates the /classes/* folder gwt:compile needs. I just need to fix my pom.xml to get the order straight (compile java classes first, then gwt:compile) Hope this helps anyone else that might run into this subtle issue.
