I just want to make simple examples like this:

 OWLOntology o = manager.loadOntologyFromOntologyDocument(file);
 System.out.println("--------------------------");
 OWLReasonerFactory rf = new ReasonerFactory();
 OWLReasoner r = rf.createReasoner(o);
 r.precomputeInferences(InferenceType.CLASS_HIERARCHY);

But ReasonerFactory is not recognized by the system.
I downloaded the jar file, installed maven, opened a netbeans project using a maven project. Why it doesn't works??

Use OWLAPI version 5.1.7 and HermiT version 1.4.3.517.

The problem here is that in the version you used ReasonerFactory is an inner class in the Reasoner class, but your test code relies on it being a standalone class. That happened in a later version of HermiT.

1.4.3.517 is the most recent release and includes a few bug fixes, hence I recommend using it in place of all the other OWLAPI 5 compatible versions.
