Claus Schrammel reopened MASSEMBLY-683:
---------------------------------------
I am sorry that I was not clear enough in my original bug report. The first
line may be misleading. *Normally* they provide the same result.
But actually the assembly plugin and Maven (maven-dependency-plugin) provide
*different* results for the given xerces issue.
Please try the attached example and compare the output of the assembly plugin
(lib folder within target/app-0.0.1-SNAPSHOT-package.zip) with the output of
the maven-dependency-plugin (target/dependency).
> dependencySet includes different versions of same dependency when there is a
> pom relocation involved

> 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.
