Description

NiFi Stateless can download extensions (NARs) from a Nexus server if they are not available locally in the extensions directory (nifi.stateless.extensions.directory).

If all NARs required by the flow are provided in the extensions directory (e.g. manually copied to a server that has no public internet / Nexus connection), no Nexus access is needed and in this case the 'nifi.stateless.extension.client.*' properties should not be mandatory. Currently it fails and does not try to load the local NARs if no extension client is configured (the failure is mentioning a NAR that is not available). It can work with a dummy nexus client URL.

The nexus property should be optional and the extensions directory should be used regardless of the existence of this property.
