[MNG-8256] ProjectDependencyGraph bug: in case of filtering, non-direct module links are lost #9606
Description
Tamas Cservenak opened MNG-8256 and commented
The FilteredProjectDependencyGraph is used to "narrow" reactor when constrained projects are used (ie use of -pl and alike of methods). The code was correct when transitive upstream or downstream in-project dependencies were asked, but in case of non-transitive ones the links were lost, if "intermediary" was removed from reactor.
In case of modules (A, B, C) and relationship A -> B -> C if active projects were only (A, C), the filtered links should result in (A -> C), unlike today, in A and C being "unrelated" that is simply no true.
