I have project A that triggers project B only if it has SVN changes (using the downstream-ext plugin).

Project B is set to be triggered by SVN changes as well.

My problem is that most of the time when I do a commit on both repositories (a commit that is meant as a whole), project B will start building before project A, even though this plugin marks it as downstream.

It would be nice that B (when it detects a trigger other the A having been built) checks to see if A has changes and needs to build. If it has changes it makes sure A runs before continuing. It should do this until A no longer has the need to build and only then it should update and run B.

In my current config B always or almost always runs too soon, before A prepares some resources for it... So it's a wasted run + then it won't build again after the correct changes are build in A because B was already updated.

Hope this long story makes sense .
