prompt: Your task is to convert the following English description into an ASCII tree format.
  
  src is a principal directory that houses 2 subdirectories: main and test.
  At the main level, 'main' keeps 1 subdirectories: antlr.
  At level 2, in directory path 'main > antlr', 'antlr' contains 1 child directories: org.
  At level 3, in directory path 'main / antlr / org', 'org' hosts 1 folders: gradle.
  At level 4, in directory path 'main → antlr → org → gradle', 'gradle' is a vacant space.
  At the main level, 'test' houses 1 folders for testing purposes.
  In nested path 'test → java', 'java' bundles 1 directories: org.
  In nested path 'test > java > org', 'org' features 1 subfolders: gradle.
  At level 4, in directory path 'test / java / org / gradle', Inside 'gradle', you'll find it remains unused.
  
  
  Format your response in this style:
  ```
  src
   +--constructors
   |   `--test
   +--hoc
   +--models
   |   `--test
   |       `--__snapshots__
