Redmine

Hello - I'm having trouble installing a ruby plugin called issue checklist. I've tried various versions of ruby (2.3, 2.4, 2.5) and I'm on RHEL 7.4 using redmine 4.0.4.

bundle exec rake redmine:plugins NAME=redmine_checklists RAILS_ENV=production

And got this output (this is in a test environment):

/home/redmine-4.0.4/plugins/redmine_issue_checklist-master/init.rb:24: warning: key :issue_checklist is duplicated and overwritten on line 24
rake aborted!

Does anyone know what might be going on?

Edit: I've also removed the '-master' from the plugin directory name and got the same result.
