Create a pypi proxy of https://bloomberg.bintray.com/pip in Nexus Repo 3.13.0, and try to download the "blpapi" package from it using pip.
This will fail. The nexus.log shows:

Note that the packages are not under a "/packages" directory. Our code is explicitly looking for that, and will not download anything that is not in a "/packages" location:
Expected: A Nexus Repo 3 pypi proxy should be able to proxy anything pip can download.
