             Summary: Dependency resolution in multimodule project
                 Key: MNG-7066
                 URL: https://issues.apache.org/jira/browse/MNG-7066
             Project: Maven
          Issue Type: Bug
          Components: Dependencies, POM
    Affects Versions: 3.6.3
            Reporter: Vasyl Danyliuk
         Attachments: maven-test.zip

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.
