Exception in thread "main" java.lang.Error: Unresolved compilation problem

Hi,

I'm interested to make some queries from SPARQL and translate it to gremlin. So I'm trying to compile sparql-gremlin using eclipse (after mvn eclipse:eclipse) and I got this exception.

Exception in thread "main" java.lang.Error: Unresolved compilation problem: The method reduce(GraphTraversal<capture#25-of ?,capture#26-of ?>, BinaryOperator<GraphTraversal<capture#25-of ?,capture#26-of ?>>) in the type Stream<GraphTraversal<capture#25-of ?,capture#26-of ?>> is not applicable for the arguments (GraphTraversal<Vertex,capture#33-of ?>, BinaryOperator<GraphTraversal<capture#25-of ?,capture#26-of ?>>) at com.datastax.sparql.gremlin.SparqlToGremlinCompiler.visit(SparqlToGremlinCompiler.java:122) at org.apache.jena.sparql.algebra.op.OpFilter.visit(OpFilter.java:103) at org.apache.jena.sparql.algebra.OpWalker$WalkerVisitor.visit1(OpWalker.java:85) at org.apache.jena.sparql.algebra.OpWalker$WalkerVisitor.visitFilter(OpWalker.java:91) at org.apache.jena.sparql.algebra.OpVisitorByType.visit(OpVisitorByType.java:112) at org.apache.jena.sparql.algebra.op.OpFilter.visit(OpFilter.java:103) at org.apache.jena.sparql.algebra.OpWalker$WalkerVisitor.visit1(OpWalker.java:83) at org.apache.jena.sparql.algebra.OpVisitorByType.visitModifer(OpVisitorByType.java:44) at org.apache.jena.sparql.algebra.OpVisitorByType.visit(OpVisitorByType.java:160) at org.apache.jena.sparql.algebra.op.OpProject.visit(OpProject.java:47) at org.apache.jena.sparql.algebra.OpWalker.walk(OpWalker.java:43) at org.apache.jena.sparql.algebra.OpWalker.walk(OpWalker.java:33) at com.datastax.sparql.gremlin.SparqlToGremlinCompiler.convertToGremlinTraversal(SparqlToGremlinCompiler.java:59) at com.datastax.sparql.gremlin.SparqlToGremlinCompiler.convertToGremlinTraversal(SparqlToGremlinCompiler.java:96) at com.datastax.sparql.gremlin.SparqlToGremlinCompiler.convertToGremlinTraversal(SparqlToGremlinCompiler.java:100) at com.datastax.sparql.ConsoleCompiler.main(ConsoleCompiler.java:105) And I am using OS X 10.12.1

My version of java is java version "1.8.0_101" Java(TM) SE Runtime Environment (build 1.8.0_101-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

Can someone give a little help to get this running please?

Cheers!
