#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
