Example task do not build (Exception: Couldn't find generator and others)

[CristianCantoro]

Description: Trying to build the tasks with CMS uninstalled is not working. Are these examples supposed to build?

Steps to reproduce:

1. clone the repository: git clone https://github.com/cms-dev/con_test.git
2. make a task: cd con_test/batch && cmsMake -a

Expected:
The task should have been build successfully.

Actual:
It didn't (see the errors below).

I have tried adding a file called generator.cpp, but I was getting the same error. The error disappeared if I renamed the file generatore.cpp (Italian name).

At that point, though, another error popped up, which was the lack of validator. Fixing also that lead to this error:

$ cmsMake -a

To clarify, if I follow the instruction in the README.md:

1. import the users with: cmsImportUser --all -L italy_yaml .
2. Import the contest and the tasks with: cmsImportContest -i -L italy_yaml .

Everything works.

The problem is that I am trying to create a new communication task, and I do not know how I am supposed to test and build this type of task.
