执行OWL API时遇到错误

我正在尝试执行以下代码。

import java.io.File;

import org.semanticweb.owlapi.apibinding.OWLManager;
import org.semanticweb.owlapi.model.AddAxiom;
import org.semanticweb.owlapi.model.IRI;
import org.semanticweb.owlapi.model.OWLAxiom;
import org.semanticweb.owlapi.model.OWLClass;
import org.semanticweb.owlapi.model.OWLDataFactory;
import org.semanticweb.owlapi.model.OWLOntology;
import org.semanticweb.owlapi.model.OWLOntologyCreationException;
import org.semanticweb.owlapi.model.OWLOntologyManager;

public class Snippet {
public static void main(String[] args) throws OWLOntologyCreationException {
    File file = new File(
            "file:///c/Users/DTN/Desktop/Final SubmissionFilteringMechanism_Ontology.owl");
    OWLOntologyManager m = OWLManager.createOWLOntologyManager();
    OWLDataFactory f = OWLManager.getOWLDataFactory();
    OWLOntology o;
    o = m.loadOntologyFromOntologyDocument(file);
    OWLClass clsA = f.getOWLClass(IRI.create("urn:test#ClassA"));
    OWLClass clsB = f.getOWLClass(IRI.create("urn:test#ClassB"));
    OWLAxiom ax1 = f.getOWLSubClassOfAxiom(clsA, clsB);
    AddAxiom addAxiom1 = new AddAxiom(o, ax1);
    m.applyChange(addAxiom1);
    for (OWLClass cls : o.getClassesInSignature()) {
        System.out.println(cls.getIRI());
    }
    m.removeOntology(o);
}
}

产生以下错误。

请一些人帮帮我。提前谢谢。

你在课程路径中包含哪些罐子？

看起来你错过了一些google guice依赖项。我建议使用一些依赖管理工具，如maven或gradle

例如，我通过使用maven依赖

解决了这个问题
  

net.sourceforge.owlapi：owlapi-osgidistribution：4.0.2

在一个以Snippet类为主类的maven项目中。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

如果要在不使用依赖关系管理器的情况下运行它，请确保在类路径中包含以下jar（使用maven依赖关系树命令获取以下列表）

答案 1 :(得分：-1)

这是一个.zip文件，其中包含OWLAPI 4.0.2的所有必需依赖项。您只需将其解压缩并在项目中包含所有这些.jar文件。

从以下网址下载.zip： https://www.dropbox.com/s/835qjm1xrhefy6s/Dependencias%20extras.rar?dl=0

最好的问候。
