Airavata API needs airavata-client.properties. Ideally we should need such configuration file

I am trying to use Airavata API as a maven dependency. But without above mentioned property file in my class path, I get following exception;

Ideally we should not have this configuration file. If we need to have this configuration file we should embed in the jar and let user use the jar as it is.

Thanks
Amila
