This is relying on an unquoted substitution being globbed.  Yuck.

The most obvious reasons this could "fail" are:

1) Under Jenkins, whatever that is, the script is running in a different
   working directory.  There aren't any files matching the glob foo* for
   it to expand to.

2) Under Jenkins, the shell is being invoked in such a way that globbing
   is disabled (set -f, set -o noglob, or something equivalent).
