def after_configure
  config.init_contents << StringIO.new("require 'shoes'\nShoes.configuration.backend = :swt\n")
end

#default_executable ⇒ String

Uses the ‘@config.run` if it exists. Otherwise, looks in the application’s ‘bin` directory for an executable with the same name as the jar. If this also fails, defaults to the first executable (alphabetically) in the applications `bin` directory.

Returns:

  • (String) —

    filename of the executable to run
