[jira] Commented: (MNG-4132) import dependencies should honor "nearest definition" resolution

["Ralph Goers (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MNG-4132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=173006#action_173006 ] 

Ralph Goers commented on MNG-4132:
----------------------------------

http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html in the section on Importing Dependencies clearly documents this behavior. At this point I don't believe it would be possible to make a behavioral change like this in 2.0.x or 2.1. However, it is my understanding that 3.0 will be doing "importing" in a very different manner.

This can either be changed to wontfix or set the fix version to 3.0.

> Maven defines a "nearest definition" approach to dependency resolution.  However, the newly introduced "import" dependencies don't.  They take a top down "first defined" approach.
> For example:
> bom1:
>  defines log4j:1.2.9
> bom2:
>  defines log4j:1.2.12
> bom3
>  imports bom1
> jar
>  imports bom3
>  imports bom2
> mvn dependency:tree in "jar" will resolve log4j:1.2.9 simply because it is first in the dependencyManagement section of the jar.  I would expect it to resolve log4j:1.2.12 since it is the "nearest definition" in this scenario.
> This is somewhat confusing because this example works differently:
> bom1
>  defines log4j:1.2.9
> jar
>  imports bom1
>  defines log4j:1.2.12
> mvn dependency:tree in "jar" will resolve log4j:1.2.12.  In this case "nearest definition" is honored.
> I've attached a test case illustrating the problem.
