Hi, Yes, I can reproduce and confirm that it is caused by MNG-6601.
The impact is minimal: it's caused by the fact that there is no "<reports/></ reports>" in the Maven site's pom.xml for the default reportset (the one that adds skip=true) This is a construct that is really unusual, then should really not impact many users: it will be fixed in a future bugfix release (please open a Jira issue if possible...). If someone is impacted and needs a quick solution, the workaround is to add this "<reports/></reports>" line to the reportset Regards, Hervé Le vendredi 12 avril 2019, 01:02:36 CEST Gabriel Belingueres a écrit : > Hi Karl.
