Tested with branch

Just making sure releases are unblocked, will update documentation later

I was previously involved in signing up for the maven deployment site account. Is that part still unchanged (the environment variables username and password? I assume it is the same.

LGTM - I'm guessing there are some minor changes required in the 'Release to the public repository' section of our documentation, too https://github.com/dtinit/data-transfer-project/blob/master/Documentation/Publishing.md#release-to-the-public-repository

Yeah, I'll change the documentation later. Just want to unblock releases for now
