Realised I had a whole folder of generated files that were part of the repository, and managed to work out how to remove them (this guide was very helpful). It was a tad nerve-wracking, but all seems to have come together ok.
Next up - working out how to use Maven to pull in dependencies at build time, so that I can remove _them_ from the repository as well, and not be including multiple versions of compiled jar files (Size of my code: 43KB. Size of included libraries 50.8MB).
