Janusgraph: Please add a key named "ConfigurationManagementGraph" to the "graphs" property

[cegprakash]

I'm getting an exception when I tried a small piece of code (my first line of code with Janus in Java) for which I couldn't find any solution

cp janusgraph-cassandra-es-server.properties JanusGraph-configurationmanagement.properties

gremlin-server-configuration.yaml

graphManager: org.janusgraph.graphdb.management.JanusGraphManager
graphs: {
  graph: conf/gremlin-server/janusgraph-cassandra-es-server.properties,
  ConfigurationManagementGraph: conf/gremlin-server/JanusGraph-configurationmanagement.properties
}

import org.janusgraph.core.ConfiguredGraphFactory;
Set<String> names = ConfiguredGraphFactory.getGraphNames();

produces the following exception

org.janusgraph.graphdb.management.utils.ConfigurationManagementGraphNotEnabledException: Please add a key named "ConfigurationManagementGraph" to the "graphs" property in your YAML file and restart the server to be able to use the functionality of the ConfigurationManagementGraph class.

    at org.janusgraph.core.ConfiguredGraphFactory.getConfigGraphManagementInstance(ConfiguredGraphFactory.java:163)
    at org.janusgraph.core.ConfiguredGraphFactory.getGraphNames(ConfiguredGraphFactory.java:119)

if I use the same property file as given in documentation

gremlin.graph=org.janusgraph.core.JanusGraphFactory
storage.backend=cassandrathrift
graph.graphname=ConfigurationManagementGraph
storage.hostname=127.0.0.1

I get this exception
