  src is a head directory that comprises 2 subdirectories: main and test.
  At the top level, 'main' carries 1 subdirectory elements: antlr.
  Within directory hierarchy 'main / antlr', 'antlr' encompasses 1 subfolders: org.
  Within directory hierarchy 'main / antlr / org', 'org' organizes 1 subdirectories: gradle.
  Within directory hierarchy 'main → antlr → org → gradle', 'gradle' sits empty.
  Back to the top level.
  At the top level, 'test' organizes tests across 1 separate subfolders.
  Within directory hierarchy 'test → java', 'java' groups 1 contained folders: org.
  At level 3, in directory path 'test > java > org', 'org' comprises 1 subfolders: gradle.
  Within directory hierarchy 'test > java > org > gradle', 'gradle' has no content.
