You could try my vps package

  http://ozymandias.dk/emacs/emacs.html#vps

It caches both the filelists and the directory list. The latter is
needed for projects that use directory recursion to avoid excessive
directory traversals. The caches are rebuilt when they become to old.

Use M-i l (vps-list-dirs) to get a buffer with all the filenames in
the current project. You can then use search, C-s, ,, , RET RET to
search for and open a file.

For fast and convenient file selection of a file in the current
project you could use anything.el combined with the vps source show
below:

 (defvar anything-source-vps-files
  '((name . "Project Files")
     (candidates . (lambda ()
                     (when vps-project-name
                       (if (not (file-exists-p (vps-filelist-filename)))
                         (error "Run M-x vps-write-filelist RET manually"))
                       (start-process "anything-source-vps-files" nil
                         "grep" "-i" (replace-regexp-in-string "^-"
                                       "."  anything-pattern)
                         (vps-filelist-filename)))))
     (type . file)
     (requires-pattern . 4))
  "Source for retrieving files (cached) vps filelist.")
