i have scala mutable set want index in elasticsearch array way in doing throwing me error here code

var genreidset = scala.collection.mutable.set[int]() genreidset+=1 genreidset+=2 genreidset+=3  val bulkrequest=client.preparebulk() bulkrequest.add(client.prepareindex("testdb","test","123")         .setsource(mymethod) ) val bulkresponse =bulkrequest.execute().actionget() def mymethod: xcontentbuilder={   def json={jsonbuilder().startobject()}  json.field("uuid","123") json.startarray("genreidset") for(n<-genreidset) {   json.value(n)   } json.endarray() json.endobject()    } 

but gives me error

please me making mistake

you can try doing

var genreidset = scala.collection.mutable.set[int]() genreidset+=1 genreidset+=2 genreidset+=3 var xb:xcontentbuilder=xcontentfactory.jsonbuilder().startobject().field("uuid",artistimpl.getuuid)       xb.startarray("getgenreidset")       for(n<-genreidset)       {           xb.value(n)         }       xb.endarray()       xb.endobject()   val bulkrequest=client.preparebulk() bulkrequest.add(client.prepareindex("testdb","test","123")         .setsource(xb) )  val bulkresponse =bulkrequest.execute().actionget()
