"Unable to find XXX.gwt.xml on your classpath" error in GWT

eclipse, gwt

Solution

It turns out that when you debug some GWT project as Web Applications, Eclipse does not append the module name (i.e. the gwt.xml file) to the list of arguments. I tried adding it manually, but forgot to add the complete package name that houses the gwt.xml file. The module should have been referred to as com.company.project.Project.gwt.xml, not just Project.gwt.xml.

Problem

After importing a Maven GWT project into Eclipse the debugger doesn't work, complaining that it's `Unable to find ProjectName.gwt.xml on your classpath` How do you fix this error?
