How to build index in a single groovy script? - groovy

Question

When I have updated my janus graph schema, I have created a property key but forgot to build the index.If I run same piece of code with this buildIndex of that property then my data will get redundant data. So I am trying to build the index directly in the gremlin console.
What I have tried is
:remote connect tinkerpop.server conf/remote.yaml
// myScript = new File('/tmp/scripts/dbscripts/campaignTypeSchema/01_campaignTypeSchema.groovy').getText('UTF-8')
// :> #myScript
:> m = graph.openManagement()
/** Getting Vertex Labels **/
:> Campaign = m.getVertexLabel('Campaign')
/** Vertex Properties creation **/
:> campaignType = graph.openManagement().getPropertyKey('campaignType')
/** Vertex supporting indexes **/
:> graph.openManagement().buildIndex('campaignTypeByCampaign', Vertex.class).addKey(graph.openManagement().getPropertyKey('campaignType')).buildCompositeIndex()
println "Finished updating schema"
:remote close
:x
But endedup with an error
Error in /tmp/scripts/dbscripts/campaignTypeSchema/run.groovy at [9: :> Campaign = m.getVertexLabel('Campaign')] - No such property: m for class: Script36

Then I have tried running directly in gremlin console
gremlin> :> graph.openManagement().buildIndex('campaignTypeByCampaign', Vertex.class).addKey(graph.openManagement().getPropertyKey('campaignType')).buildCompositeIndex()
For this I got an error saying
The vertex or type is not associated with this transaction [campaignType]

You need to create your remote connection as a session:
:remote connect tinkerpop.server conf/remote.yaml session
as described here or else variable state won't be persisted between commands.
