Google Web Toolkit 2.4.0 | Eclipse Version: Indigo Service Release 1 | Build id: 20110916-0149
Project: “guestbook” sample application present in appengine/demo folder
Error: Missing required argument ‘module[s]’
Background: I used to build/compile apps in eclipse helios. After upgrading to new google app engine sdk and eclipse getting above error while running any non – GWT application. However a simple GWT application is running correctly.
I finally found out the issue. When creating a new Google Web Application project, there are 2 options, Google Web Toolkit and Google App Engine which can be selected. I was selecting both so the project which was being created was a GWT project. So while running it was expecting a gwt module and related configuration file.
The solution was to not select “Google Web Toolkit” when creating a new Google Web Application Project.
