运行maven site的奇怪问题（处理POM时遇到问题）

Question

[WARNING] Unable to create Maven project for org.crashub:crash.shell:pom:1.3.1 from repository.
org.apache.maven.project.InvalidProjectModelException: Some problems were encountered while processing the POMs:

Answer 1

我发现了这两个相关的问题：

https://jira.exoplatform.org/browse/crash-225

https://jira.codehaus.org/browse/mshade-185

CRaSH正式嵌入为Spring Boot remote Shell。

所以org.crashub:crash.shell:pom:1.3.1似乎与Spring Boot有关，但我不知道警告是什么意思：“无法为[...]创建Maven项目”
