> "Nested imports" doesn't work on Maven 2.0.9
> --------------------------------------------

> Key: MNG-3537
> URL: http://jira.codehaus.org/browse/MNG-3537
> Project: Maven 2
> Issue Type: Bug
> Components: Artifacts and Repositories
> Affects Versions: 2.0.9
> Reporter: Yan Huang
> Fix For: 2.0.x

> The "nested imports" doesn't work on Maven 2.0.9.
> When trying to resolve "nested imports", Maven 2.0.9 kind of "forget" about
> the repositories that are defined in settings.xml and only tries to look up
> some of artifacts in "central" repository.
> Here attaches the sample. The steps to produce this bug under Maven 2.0.9:
> 1. unzip this zip and it'll create a folder called "sample". There are 5 POM
> files under there.
> 2. deploy all sample*.xml to a Maven 2 repository by using
> "deploy:deploy-file".
> 3. run "mvn help:effective-pom" and it will fail. The sample/pom.xml imports
> "sample-1.0.0.0" POM which in turn imports all other sample-pom-[1-3]
> artifacts. The error messages are as belows. It's trying to look up artifacts
> ONLY in central repository.
> >mvn help:effective-pom
