使用 Maven 构建 Class 路径失败

Question

我正在使用从 git.According 到 README.md 文件的 Knowledge Graph Identification repository，我能够使用 batsh fetchDataset.sh 下载数据集。然后我尝试构建使用以下命令使用 Maven 的类路径。

~/KnowledgeGraphIdentification/nell_lazy$ mvn dependency:build-classpath -Dmdep.outputFile=classpath.out

但是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，对于为什么我使用 maven 构建的类路径在此处失败的原因，我将不胜感激。

我不是您所在领域的专家，但您想要的 mvn 存储库似乎已移动，请查看并希望它有所帮助：

Answer 2

我刚收到这个运行并想发布解决方案。由于我是运行早期版本的 psl，我无法构建类路径，因为 KGI 工件在最新版本中不可用。

因此，对于任何新用户来说，只是一个旁注：我能够通过用这个 CANARY 版本 pom.xml 可用 here 替换 pom.xml 文件来成功构建它。除此之外，还有以下 psl 目录

psl-cli
psl-核心
psl-groovy
psl-解析器

来自 this repo 的内容需要在您正在进行的实验中可用。

然后以下将成功构建创建 classpath.out 文件的类路径

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

使用 Maven 构建 Class 路径失败
