When I try the 1st build of my project, the "svn co" command works, but after
that a "svn info trunk" is issued, which should be only "svn info" (no "trunk"),
because there´s no "trunk" directory since I am already downloading the code
from trunk. I suspect this is caused by a erroneous CVS behavior inheritage.

Here´s the console output:

[workspace] $ svn co -q --non-interactive https://trac/svn/infopae/trunk
$ svn info trunk
ERROR: no revision in the svn info output
java.io.IOException: no revision in the svn info output
