How set external gem into project using svn?

Question

I need to add gem into vendor folder as external using SVN.

Path to add gem /vendor/gem_name. Path to svn repo path_to_svn_repos/gem_name/trunk

I try to do it, but it remove all another externals and add my gem :( I need to append this gem to existing externals list.

How can I do it? Please, help

Answer 1

I add external using RubyMine:

Right click in folder, then choose 'Subversion' and 'Edit properties', and add gem with it's svn path.

And run svn up after this actions.

P.S. But I still don't know how can I do it using terminal.
