redmine 3.3

[burg-md]

We tried to use your plugin with redmine 3.3 and have some issues with rake command, after the installation of your plugin.
Could you maybe fix this?

Hi mmohme,

sorry, this plugin was not yet ported to recent redmine versions.

The specific error that you posted is probably solved by editing init.rb:
Delete the line
require 'dispatcher'
and replace
Dispatcher.to_prepare do
with
ActionDispatch::Callbacks.to_prepare do

I haven't tested this fix though and I am afraid you will run into more issues when running this plugin on a recent rails/redmine version
