java使用Maven构建类路径失败

Question

我正在与git的Knowledge Graph Identification repository合作。根据自述。md文件，我可以使用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构建的类路径在这里失败的原因，我希望能提供一些信息

Answer 1

我刚刚运行了这个程序，并考虑发布解决方案。 因为我运行的是早期版本的psl，所以我无法构建类路径，因为KGI工件在最新版本中不可用

因此，对于任何新用户，请注意以下几点： 通过用这个金丝雀版本pom.xml替换pom.xml文件，我成功地构建了它。 除此之外，还有以下psl目录

• psl cli
• psl核心
• psl groovy
• psl解析器

从this repo开始，需要在你正在进行的实验中提供

然后，下面将成功构建创建classpath.out文件的类路径

mvn dependency:build-classpath -Dmdep.outputFile=classpath.out
