Ruby - unexpected return (LocalJumpError)

Ruby 2.0

Why would the code below give unexpected return (LocalJumpError) ?

# some code here
puts "Scanning for xml files .."
zip_files = Dir.entries(directory).select { |f| File.extname(f) == '.zip' }
if(zip_files.count == 0)
    puts "No files found, exiting..."
    return
end
# more code here ( if files found)

Error: unexpected return (LocalJumpError)

No files found, exiting...
[Finished in 0.9s with exit code 1]

Alternatively, you could rescue the LocalJumpError

puts "Scanning for xml files .."
zip_files = Dir.entries(directory).select { |f| File.extname(f) == '.zip' }

begin
  return unless zip_files.count > 0

  # more code here ( if files found)
rescue LocalJumpError
  puts "No files found, exiting..."
end

You're not in a method. You cannot return from there. If you want to exit early, use exit.
