  • Platform information:
    • openHAB 5.2
    • openhabian (trixie)
    • Java Runtime Environment: OpenJDK 64-Bit Server VM (build 21.0.10+7-Debian-1deb13u1, mixed mode, sharing)
  • Issue of the topic: attempting to add a group in jruby (rule and console) fails with cannot load such file – csv (LoadError)
  • Specifically I am trying to add a group that “sum” the value of all the children which are “number” or :number

this works

group_item 'myGroup',
                   'myGroup', type: :number

this fails

group_item 'myGroup',
                   'myGroup', type: :number, function: 'sum'

Full Console Test

rb(main):001* items.build do
irb(main):002*   group_item 'myGroup',
irb(main):003*   'myGroup', type: :number, function: 'sum'
irb(main):004> end

This happens when you’re using Gemfile.

Current solution: add csv to your Gemfile

openhab> jrubyscripting bundle add csv

There’s an open PR to address this since Feb, but I haven’t got around to finalising it.
