Spring Templates in Docker Container
It appears that, by default, docker drops files as being never modified into an image. Spring has put in a sanity check on its templates to see if they've ever been updated. Executing the following commands resolved my problem, and now I'm left thinking that one of these codebases needs a bug report against it.

Adding
RUN touch my.jarto your Dockerfile will solve the problem.
