------------------------------------
Summary: ProjectDependencyGraph bug: in case of filtering,
non-direct module links are lost
Key: MNG-8256
URL: https://issues.apache.org/jira/browse/MNG-8256
Project: Maven
Issue Type: Bug
Components: Core
Reporter: Tamas Cservenak
Fix For: 4.0.0, 3.9.10, 4.0.0-beta-5
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.
