Michael Osipov commented on MNG-7066:
-------------------------------------
OK, thanks, It needs to be analyzed whether this is truly Maven Core or just
Maven Resolver.
> Dependency resolution in multimodule project

> I have a bunch of modules under parent pom. In the parent pom, there is a
> dependency management section that defines the 2.12.0 version of the Jackson
> library. However, in one of the modules (Module One), I need to downgrade the
> version to 2.10.5 due to compatibility issues. For this module, it works
> well. There is a second module(Module Two) that has a dependency on Module
> One. And for this dependency maven resolves the version of Jackson to 2.12.0.
> But Module Two actually doesn't declare a dependency on Jackson at all, just
> dependency on Module One. In the end, I'm getting compatibility issues here.
> It can be resolved by explicitly specifying a dependency on Jackson 2.10.5 in
> Module Two, but it still looks like a bug.
> I've created a very small project to demonstrate the problem. You can check
> out it here [https://github.com/DrBAXA/maven-test] or just download the
> attached archive.
> In maven-test-lib and maven-test-app there are just two test files. One of
> them fails as expecting 2.10.5 version
