【问题描述】：
我正在使用来自 git 的 Knowledge Graph Identification repository。根据 README.md 文件，我能够使用 batsh fetchDataset.sh 下载数据集。然后我尝试使用以下命令使用 Maven 构建类路径。
~/KnowledgeGraphIdentification/nell_lazy$ mvn dependency:build-classpath -Dmdep.outputFile=classpath.out
但构建失败并显示以下消息。

因此我检查了我的 Maven 和 Java 安装。
Apache Maven 3.3.9
Maven home: /usr/share/maven
Java version: 1.8.0_181, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-8-openjdk-amd64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.15.0-34-generic", arch: "amd64", family: "unix"
因此，对于我使用 maven 构建的类路径为何在此处失败，我将不胜感激。
