@wolfgang-ch is this the full stacktrace here? Can you probably share a failing example?

[wolfgang-ch]

I've attached both logs for tycho 3.0.4 and 4.0.2

Can you probably share a failing example?

I do not exactly understand what I should share but the root pom.xml file is here https://github.com/mytourbook/mytourbook/blob/main/pom.xml

@wolfgang-ch it seems Tycho can't load the repository, so I wonder if you can share the

p2 repo is created by using the export wizard for a feature in Eclipse 4.28

because that part might be the problem here, usually a P2 repos is created by Tycho itself (for wich I have no known issues right now).
