================ Step #1 =================

Cleaning output files:
  out/production/module/Base$A.class
  out/production/module/Base$B.class
  out/production/module/Base.class
  out/production/module/META-INF/module.kotlin_module
End of files
Compiling files:

End of files
Exit code: ABORT
------------------------------------------
COMPILATION FAILED
'when' expression must be exhaustive, add necessary 'is C' branch or 'else' branch instead

================ Step #2 =================

Cleaning output files:
  out/production/module/Base$A.class
  out/production/module/Base$B.class
  out/production/module/Base$C.class
  out/production/module/Base.class
End of files
