间接导入时出现 FileNotFoundException
FileNotFoundException on indirect import
我正在创建一个自定义 ontology (Ontology A)，当我尝试导入另一个我创建的 ontology 时，我得到一个关于间接导入的 "FileNotFoundException" (Ontology B)，使用 "Import an ontology contained in a specfic file." 选项。
Ontology B 在将微出版物 ontology（可在 here 中找到）下载到本地名为 micropublications.owl 的文件后成功导入。在导入 micropublications.owl 时，我使用了 "Import an ontology contained in a specfic file." 选项，一切正常。我检查了 protege 中的 "import" 部分，一切似乎都很好，即有一个特定的 "Location" 指向实际下载的文件等
当我尝试在 ontology A 中导入 ontology B 时，它失败了并且日志文件包含以下完整堆栈跟踪
