Exception when adding SWRLAPI to manipulate swrl rules in java


I have a problem when i want to add SWRLAPI or SWRL with Drools API. I added SWRLAPI, SWRLAPI with Drools and OWLAPI dependencies with maven. It seems there is a problem with SWRLAPIFactory.createSWRLRuleEngine(o); Here is my Main class

    OWLOntologyManager m = OWLManager.createOWLOntologyManager();
    File file = new File("OoEI.owl");
    OWLOntology o = m.loadOntologyFromOntologyDocument(file);
     // Create a SWRL rule engine using the SWRLAPI  
    SWRLRuleEngine ruleEngine = SWRLAPIFactory.createSWRLRuleEngine(o);
    PelletReasoner reasoner = com.clarkparsia.pellet.owlapiv3.PelletReasonerFactory.getInstance().createReasoner( o );

and here is my pom.xml :

I get this Exception :

Is there a solution ? Thanks you .


Solution

  • You have two owlapi versions on the class path, one from pellet and one explicit in your dependencies. Make sure there's only one version at runtime.
