groovy.lang.MissingPropertyException: No such property: JanusGraphFactory for class: groovysh_evaluate

Hi Benoît !

I can't really explain why but suddenly, after almost a year of working perfectly fine, this week, when trying to update the graph using the groovy scripts as every week, I got an error at the first line :

graph = JanusGraphFactory.open('conf/gremlin-server/janusgraph_cassandra_es.properties')

The workaround was to add this line just before import org.janusgraph.core.JanusGraphFactory

I had to do it in the clean.groovy and load_data.groovy files. (You had it in create_schema.groovy but not the other ones). It took care of the error.

So I found the fix but I don't know why it started behaving like that just this week. We haven't upgraded anything... just made a few changes in ElasticSearch configuration for optimisation purposes and restarted everything. Or maybe it is because I had to clear gremlin-server log in the meantime...
