External mercurial repository in redmine?

Is this possible to have external mercurial repository in redmine just like svn?

For svn i've got following configoration options and it work with external repos:

For mercurial i can only enter local path to r开发者_如何学Cepository:

I don't think this is possible, you will need a local clone as stated in the Redmine documentation:

Mercurial repository

To synchronize with a Mercurial repository, you will have to have a local clone of the repository on the same server you have Redmine installed on. Let's say you put Redmine in /var/www/redmine.example.com/www and have put your mercurial repository in /var/www/sources.example.com/repo/example, you would have to select Mercurial as a SCM, then enter /var/www/sources.example.com/repo/example in the repository text box.

A similar question has been asked in the Redmine forums. You'll need to set up a local clone and update it automatically, e.g. by using a cron job.
