Dependency poms not timely merged with parents
----------------------------------------------
Key: MNG-2743
URL: http://jira.codehaus.org/browse/MNG-2743
Project: Maven 2
Issue Type: Bug
Affects Versions: 2.0.4
Reporter: Kenney Westerhof
Priority: Blocker
POM's of dependencies are not properly merged with their parents.
It could be that they're not merged at all, or only partly. Since the code to
merge poms is the same
everywhere, and <repository> tags are merged for local poms, I fear that
they're not merged at all.
With this setup:
* local workspace:
** project A
*** depends on remote artifact B, residing in 'central'
* repository central:
** artifact B (cocoon-core)
*** has parent P (cocoon), also here at central
*** declares a dependency on D, residing in repo R (not a standard repository)
** pom P, declares repository R
* repository R:
** artifact D (avalon-framework-impl)
*** declares dependency on lib L, also here at repository R
** artifact L (avalon-framework-api)
When running mvn install on local project A, observe the following log:
{nopaste}
....
// cocoon-core has been resolved, now it's dependency poms are resolved:

[DEBUG] Artifact resolved
{nopaste}
The problem here is that the jar is now available in the local repo, but the
pom is not, and the dependencies of D aren't downloaded.
It seems pom B is only merged with P _after_ all dependency poms for B have
been resolved.
