Carsten Behring commented on MRELEASE-654:
------------------------------------------
As a workaround, I get a different behavior when I copy a pom.xml into the
current directory.
So it seems that maven does something with the "current project" (= project in
current directory),
instead of only working on the "checked out" sources in target/checkout.
