Run project with Spark and maven

I'm trying to run my class java that read a GML file and I use Tinkerpop and GMLReader for that , the problem is when I try to run it with spark it gives me an exception
I wrote a simple code for testing :

 public static void main(String[] args) throws IOException {
    TinkerGraph graphs = new TinkerGraph();
    String in = "/home/salma/Desktop/celegansneural.gml";
    GMLReader.inputGraph(graphs, in);
    System.out.println(graphs);
 }

The command that I'm using to run the class :

root@salma-SATELLITE-C855-1EQ:/usr/local/spark# ./bin/spark-submit --class graph_example.WordCount --master local[2] ~/workspace/graph_example/target/graph_example-0.0.1-SNAPSHOT.jar

Error :

You have to provide the dependency containing the TinkerGraph implementation. If I'm not mistaken, you need to provide this jar

Then you run spark-submit as usual but with --jars /some/location/blueprints-core-2.6.0.jar

It is explained in the official documentation :

When using spark-submit, the application jar along with any jars included with the --jars option will be automatically transferred to the cluster.
