This works, though I know approximately nil (didja see what I did
there) about elisp:

#+begin_src ox-taskjuggler.el

(defun org-taskjuggler--build-project (project info)
  "Return a project declaration.
PROJECT is a headline.  INFO is a plist used as a communication
channel.  If no start date is specified, start today.  If no end
date is specified, end `org-taskjuggler-default-project-duration'
days from now."
  (format "project %s \"%s\" \"%s\" %s %s {\n}\n"
          (org-taskjuggler-get-id project info)
          (org-taskjuggler-get-name project)
          ;; Version is obtained through :TASKJUGGLER_VERSION:
          ;; property or `org-taskjuggler-default-project-version'.
          (or (org-element-property :VERSION project)
              org-taskjuggler-default-project-version)
          (or (org-element-property :START project)
              (format-time-string "%Y-%02m-%02d"))
          (let ((end (org-element-property :END project)))
            (or (and end (format "- %s" end))
                (format "+%sd" org-taskjuggler-default-project-duration)))))

#+end_src

I don't know why the org-taskjuggler-get-start function works for the
task definition and not the project definition... but just looking for
the contents of the :start: and :end: properties directly is my
current hack. I'll leave it like that just so I don't have to manually
change the .tjp file at every export, but I'm sure there's a "proper"
way to fix :)
