Cannot create index in JanusGraph

Question

I've installed JanusGraph 0.5.2 with ScyllaDB 4.2.1 and Elasticsearch 6.6.0 and I'm trying to create a fulltext index according to the docs as follows:

1. mgmt = graph.openManagement()
2. PropertyKey value = mgmt.makePropertyKey('value').dataType(String.class).make()
3. mgmt.buildIndex('verticesByValue', Vertex.class).addKey(value, Mapping.TEXT.asParameter()).buildMixedIndex("search")
4. mgmt.commit()

It throws this error after I enter the 3. step:

No signature of method: org.janusgraph.graphdb.database.management.ManagementSystem$IndexBuilder.addKey() is applicable for argument types: (org.apache.tinkerpop.gremlin.structure.T$4, org.janusgraph.core.schema.Parameter) values: [value, mapping->TEXT]

Answer 1

Instead of:

PropertyKey value = mgmt.makePropertyKey('value').dataType(String.class).make()

Use This:

value = mgmt.makePropertyKey('value').dataType(String.class).make()

I was able to generate the issue when I used "PropertyKey" type to assign to value.
