Changing the plugin load path from a plugin-init.rb


I'm in the middle of converting one of my Rails-Apps to a plugin/ engine. Because this new plugin requires a lot of plugins I moved them to RAILS_ROOT/vender/plugins/my_plugin/plugins and added

config.plugin_paths += %W( #{RAILS_ROOT}/vendor/plugins/my_plugin/ plugins )

to my RAILS_ROOT/config/environment.rb. To reduce the necessary logic in the surrounding Railsapp I want to move this to my plugin too. To put it in the init.rb of my plugin doesn't work. Is there an other way to set this paths??

Best regards, Mark
