"Only local files are supported as R2RML mapping files"

[santifrid]

Hi everyone, I've been working with ontop CLI with MacOS for a while, and I've just bought a Windows PC. I've downloaded and configured ontop as I did before, I set up the ontop directory in my PATH, and when I run the following command:
ontop materialize -p C:/Users/USER/Downloads/map.properties -m C:/Users/USER/Downloads/map.ttl -p C:/Users/USER/Downloads/output.rdf
I get this message:
it.unibz.inf.ontop.exception.InvalidOntopConfigurationException: Currently only local files are supportedas R2RML mapping files.
I tried moving the files to C:/ but I can't seem to get it to work. Any ideas? Anyone successfully working with ontop on Windows that could help me out? Should I use WSL instead?
