The readme states in requirements a on premise system waht seems not to be working

If the adt plugin does not work with on premise, even the backend was downloaded and activated, please change the REQUIREMENTS in the readme , where a on premise system is mentioned.

On other sources it is said taht is only works in (SAP) Cloud .

If it si possible to activate the backend client on premise, then it would be nice to know how to do that.
