The download link for the LabKey Remote Java API source code seems to just download a .zip that contains the .html reference files, but no actual source code.

Hi Dennis,
Thanks for bringing that to our attention.
I've attached the Remote Java API source code file for LabKey 17.2 below and will be working to correct that so both the docs and the source are provided for the future.
