Исключение в потоке "главный" java.lang.NoSuchMethodError: org.openrdf.query.algebra.Var.isConstant() Z

Question

Я пытаюсь запустить простой Tinkerpop код

public class Main { 
    public static void main(String args[]) { 

    try { 

     TinkerGraph graph = new TinkerGraph(); 

     //Neo4jGraph graphh = new Neo4jGraph("C://Users//ZXZ//Desktop//neo4j"); 

     Sail sail = new GraphSail(graph); 

     sail.initialize(); 
     ValueFactory vf = sail.getValueFactory(); 
     SailConnection sc = sail.getConnection(); 
     sc.begin(); 

     sc.addStatement(vf.createURI("http://tinkerpop.com#1"), 
       vf.createURI("http://tinkerpop.com#knows"), 
       vf.createURI("http://tinkerpop.com#3"),

       vf.createURI("http://tinkerpop.com#name"),

     System.out.println("get statements: ?s ?p ?o ?g");

     System.out 
       .println("\nget statements: http://tinkerpop.com#3 ?p ?o ?g"); 
     results = sc.getStatements(vf.createURI("http://tinkerpop.com#3"), 
       null, null, false); 
     while (results.hasNext()) { 
      System.out.println(results.next()); 
     } 

     System.out 
       .println("************************************************************************"); 

     SPARQLParser parser = new SPARQLParser(); 
     CloseableIteration<? extends BindingSet, QueryEvaluationException> sparqlResults; 
     String queryString = "SELECT ?x ?y WHERE { ?x <http://tinkerpop.com#knows> ?y }"; 
     ParsedQuery query = parser.parseQuery(queryString, 
       "http://tinkerPop.com"); 

     System.out.println("\nSPARQL: " + queryString); 
     sparqlResults = sc.evaluate(query.getTupleExpr(), 
       query.getDataset(), new EmptyBindingSet(), false); 

     while (sparqlResults.hasNext()) { 
      System.out.println(sparqlResults.next()); 
     } 

     sc.rollback(); 
     sc.close(); 
     graph.shutdown(); 
     sail.shutDown(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 

}

но получение следующих ИСКЛЮЧЕНИЯ

Что бы быть причиной исключения?

Answer 1

Я уверен, что это делать с этой линии:

CloseableIteration<? extends BindingSet, QueryEvaluationException> sparqlResults; 

В частности, этот бит линии,

<? extends BindingSet, QueryEvaluationException> 

Попробуйте взглянуть туда, вы можете решить эту проблему.
