Note, switching back to an older version works:

  <extension>
    <groupId>org.eclipse.tycho.extras</groupId>
    <artifactId>tycho-pomless</artifactId>
    <version>2.0.0</version>

Can you provide an integration-test to demonstrate the issue? Have you tried it with a fresh local repository?

@guw also consider trying tycho 3.0. As no further infromation is provided an no one else complained I'll close this for now, let me know if you still see issues so we can reopen the ticket.
