Tamas Cservenak commented on MNG-7840:
--------------------------------------
Am pretty much sure relocation like this is not intended to work on "currently
worked on" projects (I mean, why not just edit the project POM and fix parent?
Relocation is applied on _consumed_ artifacts, so that that are NOT part of the
reactor (while your relocated POM comes as part of building POM for "this"
build, even if parent pom itself is not part of reactor, the resulting model
is).
