I have the following code in my spec helper:
SimpleCov.formatter = SimpleCov::Formatter::MultiFormatter[
rescue LoadError => error
raise error unless error.path == 'coveralls'
It does not work on JRuby in 2.0 mode, but works just fine on MRI 2.0 and trunk.
Indeed...a 2.0 feature not listed in NEWS that we did not implement.
Fix #666 by implementing LoadError#path and related load logic.
