Hi Hervé,
you can reproduce the issue on mojohaus parent repository
(github.com:mojohaus/mojo-parent.git) and using the branch "issue-105"
and just:
mvn site site:stage
Using Maven 3.5.2 fails with the described issue.
Kind regards

uh, strange: maven-site-plugin ITs are ok with many Maven and JDK versions [1]
I'll need some time to investigate

Hi to all,
I've stumbled upon the following problem during the site generation

This can be reproduced with 3.0.5 up to 3.6.1.
Versions 3.6.2 and 3.6.3 are working fine.
This means using maven-site-plugin 3.9.0 only working with Maven 3.6.2+
...in contradiction to the site[1] which says it is requirement 3.0..
Or has someone a different explanation for this?
Kind regards
