java.lang.ClassNotFoundException: org.eclipse.acceleo.module.sample.Activator cannot be found by org.eclipse.acceleo.module.sample_1.0.0.qualifier

The most likely reason I can think of is that you have used the File > New Plug-in Project wizard and kept most of the default values, yet afterwards removed (or renamed) the "Activator" class that it created in your project.

The META-INF/MANIFEST.MF file of your project should contain a line that looks like :

And if it does, it most likely shows a warning or error on that line. You can either remove the line altogether or make sure you indeed have a plug-in activator with that qualified name.
