After importing an existing project into RubyMine, I encountered \"Rails server launcher wasn\'t found in the project\" when I Run/Edit Configuration.

My variant to solve same problem.
Create new run configuration, but use "Ruby" template instead of "Redmine":
Ruby script field set to path to your redmine rails bin path and Script arguments set to "server -b 127.0.0.1 -p 3000 -e development" for ex.
