Tamas Cservenak commented on MNG-7818:
--------------------------------------
This issue does not mention this explicitly, but I can imagine one case:
* the project imports maven POM
* by looking at refd
https://github.com/apache/maven/commit/924dbfecf87fa7cc3cc21c840057272321440ea8
there ARE exclusions added in depMgmt, but also added excplicit test scoped dep
on "proper" (2.2) hamcrest. All this happened to exclude proper old 1.x
hamcrest and make sure Maven use 2.2
* This means (given affected project relies on depMgmt imported from maven
parent POM, if my assumption is true) that affected project simply needs to
"redo" what in commit above is done: re-add dependency on hamcrest core
> [REGRESSION] maven improperly excludes hamcrest-core from junit
