I am trying to connect Java to Neo4J for a project. I want to connect an already existing Neo4J database (local) to Java but I have the following error :

public class Main {

        //GraphDatabaseFactory dbFactory = new GraphDatabaseFactory();

        File p = new File("/home/etudiants/helloStackOverflow/workspace/projetnosql/graph.db");

        GraphDatabaseService db = new GraphDatabaseFactory().newEmbeddedDatabase(p);

        db.shutdown();



        System.out.println("ça marche!!!!!");

        try (Transaction tx = db.beginTx()) {

            // Perform DB operations

            System.out.println("ça marche 2");

            tx.success();

        }

    }

}

Apparantly the problem comes from a missing dependency to satisfy the class org.neo4j.kernel.api.index.IndexProvider but there kernel-api dependency is specified.

Do you have any idea how I could fix this problem?

Additional informations :

• IDE : Intellij




• Maven : v1.8




• Neo4J : v3.4.9

I hope I provided enough information so you can give me suggestion on how to fix the problem.
