It turns out that maven looks for a site_en.xml for my parent project on archiva and archiva seems to generate a return file which is actually an error message.
The maven site plugin then tries to parse it and fails horribly :(
I worked around this by just adding the following content to src/site/site_en.xml in my parent project and everything was well!
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/DECORATION/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/DECORATION/1.0.0 http://maven.apache.org/xsd/decoration-1.0.0.xsd">
<body>
</body>
</project>
I got really frustrated by this cryptic error message. I wanted to bash my head against the table and throw my laptop against the wall. Instead I cried out to God and not long after that I figured it out. Some would say thats just coincidence, I say: "Thank God", "Praise God" and "Why didn't I ask You sooner?".
