App does not work after build

[Sławek]

Basically nothing happens after my application is build by app:build command.

My steps to reproduce:

Input:

composer create-project --prefer-dist laravel-zero/laravel-zero .
php application app:rename else
[... develop custom command `import` ...]
php else 

Output:

unreleased

  USAGE: else <command> [options] [arguments]

  import                 Custom CSV Importer

Input:

php else app:build
./builds/else

Output is empty

Input:

./builds/else -vvv

Output:
