scoping details...
  • 12 extensions are included in analyses: java, gradle, md, txt, properties, yml, clj, xml, css, jsp, gitignore, bat
  • 7 criteria are used to exclude files from analysis:
    • exclude files with path like ".*/gradle/wrapper/.*" (Gradle) (1 file).
    • exclude files with path like ".*/git[-]commit[-]trailers[.]txt" (Git history trailers) (1 file).
    • exclude files with path like ".*/cache/.*" (Caches) (16 files).
    • exclude files with path like ".*/git[-][a-zA-Z0-9_]+[.]txt" (Git data exports for sokrates analyses) (1 file).
    • exclude files with path like ".*/_sokrates/.*" (Sokrates files) (0 files).
    • exclude files with path like ".*/_sokrates_landscape/.*" (Sokrates landscape files) (0 files).

About This Analysis
learn more about scopes (main, test, generated, build, other)...

  • The main category contains all manually created source code files that are being used in the production.
  • Files in the main category are used as input for other analyses: logical decomposition, concerns, duplication, file size, unit size, and conditional complexity.
  • Test source code files are used only for testing of the product. These files are normally not deployed to production.
  • Build and deployment source code files are used to configure or support build and deployment process.
  • Generated source code files are automatically generated files that have not been manually changed after generation.
  • While a source code folder may contain a number of files, we are primarily interested in the source code files that are being written and maintained by developers.
  • Files containing binaries, documentation, or third-party libraries, for instance, are excluded from analysis. The exception are third-party libraries that have been changed by developers.
