NoSuchMethodError ： org.semanticweb.owlapi.model.OWLDisjointClassesAxiom.getOperandsAsList((
我想创建一个不满意的类，并使用 HermiT 推理器列出它。我浏览了一些示例代码并设法编写了一个。

当我尝试浏览文件的行号时，发现源附件中缺少一些行号，例如：

我将 eclipse 配置为使用 java-8-openjdk-amd64。我是 OWLAPI 和 Java 8 流的新手。谁能解释导致此问题的原因以及如何解决它？
尝试将 owlapi-distribution 升级到 5.1.3 或更高版本，如下所示：
<dependency>
<groupId>net.sourceforge.owlapi</groupId>
<artifactId>owlapi-distribution</artifactId>
<version>5.1.3</version>
</dependency>
此提交自 5.1.3 以来引入了getOperandsAsList()。
