location-mapping.ttl missing

[VladimirAlexiev]

https://github.com/atextor/owl-cli/releases/download/snapshot/owl-cli-snapshot.jar gives this warning on every run:

DEBUG org.apache.jena.riot.system.stream.JenaIOEnvironment -- Failed to find configuration: location-mapping.ttl;location-mapping.rdf;etc/location-mapping.rdf;etc/location-mapping.ttl

It is annoying, and also mangles STDOUT output: #14

@atextor Sorry, wrong project! Can you move this to https://github.com/atextor/owl-cli, or I should recreate it there?

[atextor]

I have moved the issue to owl-cli.
Yes, this should not happen, DEBUG messages should only be displayed with the -vvv switch.

What is the "location-mapping.ttl" file? Where should it be stored?

[atextor]

Apache Jena, the RDF library underlying owl-cli, has a built-in mechanism to load RDF files that are referenced using URIs such as "file:myfile.ttl". When a location-mapping.ttl file is provided, it can determine for each such logical location URI a physical location (i.e., a file system location). You can find more information about this in https://jena.apache.org/documentation/notes/stream-manager.html.
If it can't find this purely optional file, Jena logs this as a debug statement. owl-cli users are not supposed to see this message by default, which is what this bug is about.
