                        WARNING
Detected that jasmine rake tasks have been loaded twice.
This will cause the 'rake jasmine:ci' and 'rake jasmine' tasks to fail.

To fix this problem, you should ensure that you only load 'jasmine/tasks/jasmine.rake'
once. This should be done for you automatically if you installed jasmine's rake tasks
with either 'jasmine init' or 'rails g jasmine:install'.
