same dependency when there is a pom relocation involved

-----------------------------------------------
Hi, now i got your point sorry was a misunderstanding on my site.
Lets dive into it. If i use maven-dependency-plugin:2.4 you will a thing like this:
{code}
$ mvn org.apache.maven.plugins:maven-dependency-plugin:2.4:tree
[INFO] Scanning for projects...
[INFO]
[INFO] ------------------------------------------------------------------------
[INFO] Building app 0.0.1-SNAPSHOT
[INFO] ------------------------------------------------------------------------
[INFO]
[INFO] --- maven-dependency-plugin:2.4:tree (default-cli) @ app ---
[INFO] acme.demo:app:jar:0.0.1-SNAPSHOT
[INFO] +- junit:junit:jar:4.11:test
[INFO] | \- org.hamcrest:hamcrest-core:jar:1.3:test
[INFO] +- acme.demo:lib-a:jar:0.0.1-SNAPSHOT:compile
[INFO] | +- log4j:log4j:jar:1.2.16:compile
[INFO] | \- xerces:xerces:jar:1.4.4:compile
[INFO] \- acme.demo:lib-b:jar:0.0.1-SNAPSHOT:compile
[INFO] \- xerces:xercesImpl:jar:2.0.2:compile
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
{code}
But if you use maven-dependency-plugin:2.5 you will get the following:
{code}
$ mvn org.apache.maven.plugins:maven-dependency-plugin:2.5:tree
[INFO] Scanning for projects...
[INFO]
...
[INFO] --- maven-dependency-plugin:2.5:tree (default-cli) @ app ---
[INFO] acme.demo:app:jar:0.0.1-SNAPSHOT
[INFO] +- junit:junit:jar:4.11:test
[INFO] | \- org.hamcrest:hamcrest-core:jar:1.3:test
[INFO] +- acme.demo:lib-a:jar:0.0.1-SNAPSHOT:compile
[INFO] | +- log4j:log4j:jar:1.2.16:compile
[INFO] | \- xerces:xerces:jar:1.4.4:compile
[INFO] \- acme.demo:lib-b:jar:0.0.1-SNAPSHOT:compile
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
{code}
If you use maven-dependency-plugin:2.6?2.8 you will get the same results which is related to [MSHARED-167 |http://jira.codehaus.org/browse/MSHARED-167]

> Key: MASSEMBLY-683
> URL: https://jira.codehaus.org/browse/MASSEMBLY-683
> Project: Maven Assembly Plugin
> Issue Type: Bug
> Components: dependencySet
> Affects Versions: 2.4
> Environment: Embedded Maven 3.0.4 in Eclipse Kepler and Maven 3.0.4 on Jenkins. All on Windows 7 with Oracle JDK 7.
> Reporter: Claus Schrammel
> Assignee: Karl Heinz Marbaise
> Attachments: acme.demo.zip
>
>
> When dependencySets are resolved, the assembly plugin handles different versions of the same artifact and provides the same result as Maven built-in dependency resolution does.
> But it fails if the artifact is relocated in its pom. The attached example shows this for xerces:xerces.
> The app depends on lib-a, which itself depends on xerces:xerces:1.4.4.
> The app also depends on lib-b, which itself depends on xerces:xerces:2.0.2, but that is relocated to xerces:xercesImpl.
> So the dependencySet on app contains xerces-1.4.4 *and* xercesImpl-2.0.2, causing problems on the classpath of the actual application.
> The demo contains a standard case with 2 different log4j version which is working fine.
> The demo also uses the maven-dependency-plugin that is able to resolve the dependencies correctly. Only xerces-1.4.4 goes into the target/dependency folder.
