Redmine

Hi!
I'm looking for the way to send notifications about project changes via jabber. It's very good if i can change project details via jabber using sprcial commands. Here is my version info:

Environment:
Redmine version 2.4.0.stable
Ruby version 2.0.0-p481 (2014-05-08) [i386-mingw32]
Rails version 3.2.15
Environment production
Database adapter SQLite

But I can't find anything working with 2.4. I tried this: https://github.com/pmisters/redmine_xmpp_notifications and https://github.com/paalvibe/redmine_jaconda_notifications but I couldn't make them work. When I copy plugin folder to the plugins folder, the Redmine just doesn't start. I tried to make a migration, like here: http://www.redmine.org/projects/redmine/wiki/Plugins but it gives errors. Can anyone help please?
