prompt: Your task is to convert the following English description into an ASCII tree format.
  
  requiring-features is a principal directory that collects 3 subdirectories: groovy, kotlin and tests.
  In the root directory, 'groovy' includes 2 contained folders: consumer, producer.
  Within directory hierarchy 'groovy > consumer', 'consumer' stands empty.
  Within directory hierarchy 'groovy > producer', Inside 'producer', you'll find it is an empty container.
  Back to the top level.
  At the main level, 'kotlin' retains 2 subfolders: consumer, producer.
  At level 2, in directory path 'kotlin → consumer', The 'consumer' repository hasn't been filled with any content.
  At level 2, in directory path 'kotlin > producer', 'producer' is barren.
  At the main level, 'tests' has no folders inside.
  
  
  Format your response in this style:
  ```
  gradle
   +--api
   |   `--internal
   |       `--initialization
   |           `--loadercache
