Is there a way to tell Dropbox not to upload a certain file? (Eclipse related)

Question

I am trying to sync a code project between two computers, one running Windows and the other running Ubuntu 12.04. I use Eclipse on both machines, but the .metadata folder produced by Eclipse is causing Eclipse to crash because of OS incompatibilities.

I was wondering if there is a way to tell Dropbox to "ignore this folder" or something like that. Or maybe have it ignore all hidden files.

Using the Official Dropbox Command Line Interface (CLI)

PROMPT$ dropbox help exclude dropbox exclude [list] dropbox exclude add [DIRECTORY] [DIRECTORY] ... dropbox exclude remove [DIRECTORY] [DIRECTORY] ...  "list" prints a list of directories currently excluded from syncing. "add" adds one or more directories to the exclusion list, then resynchronizes Dropbox. "remove" removes one or more directories from the exclusion list, then resynchronizes Dropbox. With no arguments, executes "list". Any specified path must be within Dropbox.
