The resulting service model Java classes generated by src\main\java\com\aquaticinformatics\aquarius\sdk\timeseries\create_service_models.sh includes IHttpFile properties for any POST request which supports file uploads.
These classes won't compile. The classes just need to be stripped of the IHttpFile properties, and their getters and setters, and then the SDK code is fine.
While this is a quick manual edit, taking only a minute, it is something that should be automated so that a new SDK can be regenerated without intervention.
