[jira] [Updated] (MNG-6860) Internal Error verifying Doxia site
[ https://issues.apache.org/jira/browse/MNG-6860?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Herve Boutemy updated MNG-6860:
-------------------------------
Summary: Internal Error verifying Doxia site (was: Internal Error verifying doxia)
> Internal Error verifying Doxia site
> -----------------------------------
>
> Key: MNG-6860
> URL: https://issues.apache.org/jira/browse/MNG-6860
> Project: Maven
> Issue Type: Bug
> Affects Versions: 3.6.1
> Reporter: Elliotte Rusty Harold
> Priority: Major
> Fix For: 3.6.3
>
>
> Checked out doxia-site from [https://github.com/apache/maven-doxia-site] and ran mvn verify on Linux with JDK 8.
>
> I estimate there's three different errors here to make this happen. This issue is for whatever in core is causing an InternalErrorException when likely faced with a somehow broken project setup.
