Actually both: while I succeeded in using mvn jetty:effective-web-xml 
(but didn't use it, see below), I failed to do that from inside docker 
container (see attached file)

I skipped the lazy generation because what I need is to make it faster 
from the first run: I'm in the process of implementing continuous 
delivery and webapps have to restart as fast as possible

Ah good to know: then I suppose that, with a pregenerated file, I won't 
see that line any longer

docs also mention that that output may contain stuff found on jars 
included by maven but which are not included in the war: that's why I 
tried it to see what was its output and then looked for ways to make it 
"more right"

Indeed I do and, time permitting, I'll make one
