Antoine Toulme commented on BUILDR-266:
---------------------------------------

Ketan had removed this method before from our mirror of Buildr:

http://github.com/eclipse/buildr4eclipse/commit/2d2d9bbd8ea80d2f008dbd5948c9ea265887744c

> puts with no message triggers a warning.

>                 URL: https://issues.apache.org/jira/browse/BUILDR-266
>             Project: Buildr
>          Issue Type: Bug
>    Affects Versions: 1.3.4
>            Reporter: Antoine Toulme
>            Priority: Minor
>
> We use buildr in conjunction with Cucumber. We run our tests with it. We face 
> an issue when running rake features, the default task to run all the cucumber 
> .feature files, it shows this message:
> ./features/step_definitions/../../buildr/spec/spec_helpers.rb:49: warning: 
> multiple values for a block parameter (0 for 1)
>       from 
> /Library/Ruby/Gems/1.8/gems/cucumber-0.1.16/bin/../lib/cucumber/formatters/pretty_formatter.rb:41
> cucumber actually outputs a few empty lines: @io.puts
> That doesn't seem to do too well with your code here:
>  define_method severity do |message|
>           $messages ||= {}
>           ($messages[severity] ||= []) << message
>         end
