Expecting URI in variable: [cassandra.config].

janusgraph-cassandra-embedded-server.properties

gremlin.graph=org.janusgraph.core.ConfiguredGraphFactory

storage.backend=embeddedcassandra

storage.conf-file=conf\\cassandra.yaml

graph.graphname=ConfigurationManagementGraph

I'm initializing graph in java. Now if "storage.conf-file" is set like above, then CassandraEmbeddedStoreManager creates URL "file://<base_dir>/conf/cassandra.yaml". This is not working on windows as it requires file:/// instead of file://. On the other hand if I change the value to file:\\\<base-dir>\conf\cassandra.yaml, then JanusGraphManager changes the value to "<base-dir>/file:/<base-dir>\conf\cassandra.yaml".

What should be done in this case? How can I get the correct URL with the above mentioned configurations?

Thanks
