I have a lot of maven builds and all they include "Build whenever a SNAPSHOT dependency is built" option.
But for some pairs of connected builds this option doesn't work.
I even don't know where to look for errors.
When I open parent task I see that it has child task in downstream builds section but after successful build child task is not triggered.
The most strange that for some pairs this works, for some - not.

The reason of this seems to be discussed in JENKINS-6174.
What I want to have.

1. When I open parent task - I shouldn't see any relation that is not to be triggered in this way.
2. As current "Build whenever a SNAPSHOT dependency is built" chooses just one downstream project - I'd like to have another option that works as expected - builds absolutely each downstream project.
