执行OWL API时获取错误

Question

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);
}
}

它正在生成以下错误。

线程“main”java.lang.NoClassDeffounder异常错误：com/google/inject/provider在java.lang.ClassLoader.DefineClass1（本机方法）在java.lang.ClassLoader.DefineClass（未知源）在java.net.URLClassLoader.DefineClass（未知源）在java.net.URLClassLoader.DefineClass（未知源）在java.net.URLClassLoader.Access$100（未知源）在java.net.URLClassLoader.Access$1（未知源）在00（未知源）在java.net.URLClassLoader$1处。运行（未知源）在java.net.URLClassLoader$1处运行（未知源）在java.security.AccessController.DOPrivileged（本机方法）在java.net.URLClassLoader.FindClass（未知源）在java.lang.ClassLoader.LoadClass（未知源）在sun.misc.Launcher处$AppClassLoader.LoadClass（未知源）在test.main（test.java:18)处

请有人来帮帮我。提前道谢。

在类路径中包含哪些JAR？

看起来您缺少了一些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依赖项来解决这个问题

net.sourceforge.owlapi：owlapi-osgiDistribution：4.0.2

将代码段类作为主类的maven项目。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>fake</groupId>
<artifactId>fake</artifactId>
<version>0.0.1-SNAPSHOT</version>
<build>
    <sourceDirectory>src</sourceDirectory>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
            </configuration>
        </plugin>
    </plugins>
</build>

<dependencies>
  <dependency>
    <groupId>net.sourceforge.owlapi</groupId>
    <artifactId>owlapi-osgidistribution</artifactId>
    <version>4.0.2</version>
  </dependency>
</dependencies>

null

如果您想在不使用依赖项管理器的情况下运行它，请确保在您的类路径中有以下JAR（以下列表是通过maven依赖项树命令获得的）
