I used
bin/gremlin-server.sh -i com.michaelpollmeier orientdb-gremlin 3.2.3.0
and set the following in my configuration:
graphs: {
graph: org.apache.tinkerpop.gremlin.orientdb.OrientGraph}
but I get the error:
[WARN] DefaultGraphManager - Graph [graph] configured at [org.apache.tinkerpop.gremlin.orientdb.OrientGraph] could not be instantiated and will not be available in Gremlin Server. GraphFactory message: The location configuration must resolve to a file and [org.apache.tinkerpop.gremlin.orientdb.OrientGraph] does not

value of "graphs" is a Map where the key is the name to use as a reference in Gremlin Server (in this case it is just "graph") and the value should be a .properties file that has a graph configuration in it, like this one for TinkerGraph:
The configuration options available to you there are specific to OrientDB but at a minimum you need an entry like:
gremlin.graph=org.apache.tinkerpop.gremlin.orientdb.OrientGraph

Thanks for your response Stephen,
I am getting this error log after setting up orientdb properties file.

any chance you are using a mix-matched version of Gremlin Server and OrientDB:

The orientdb-gremlin module at 3.2.3.0 is at TinkerPop 3.2.3:
which means Gremlin Server 3.2.3. I guess the two are not compatible given a groovy version bump. If you need to use a newer version of Gremlin Server you could try to remove the conflict, by cleaning up dependencies in the Gremlin Server path (/lib and /ext) directories.
