I have maven 3 task 'clean' configured that is first in the build Stage

The Maven 3 goal is set like this:
--fail-never clean

I expect the clean to fail because of the project refactoring of other reasons. This should not fail the build execution.

But in fact the build is still failing:
This is the fragment from the log:

23-Jun-2011 14:41:39 [ERROR] After correcting the problems, you can resume the build with the command
23-Jun-2011 14:41:39 [ERROR] mvn <goals> -rf :pyx-entity-gae
23-Jun-2011 14:41:39 [INFO] Build failures were ignored.
