Ceedling Configuration issues

[BenWhite-Price]

Hi,
I'm attempting to set up a new Ceedling project. I have a docker machine tied into my jenkins pipeline that is supposed to build and test the project. When I run ceedling clobber, I get this error:

ceedling clobber
🚧 Loaded project configuration from working directory.
 > Using: /home/user/workspace/project/project.yml
 > Working directory: /home/user/workspace/project

🧨 EXCEPTION: uninitialized constant PROJECT_USE_DEEP_DEPENDENCIES

if PROJECT_USE_DEEP_DEPENDENCIES
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Did you mean?  PROJECT_USE_DEEP_PREPROCESSOR

Ruby version:

ruby -v
