Cannot automatically resolve version for transitive dependencies
----------------------------------------------------------------
Key: MDEP-110
URL: http://jira.codehaus.org/browse/MDEP-110
Project: Maven 2.x Dependency Plugin
Issue Type: Bug
Components: unpack
Affects Versions: 2.0-alpha-4
Reporter: Daniel Siegmann
Assignee: Brian Fox
Priority: Minor
Attachments: unpack-test.zip
When using dependency:unpack it is not normally necessary to specify the
version for dependencies - the version is determined from settings in the POM.
However, this does not work for transitive dependencies.
For example, consider modules A and B with a dependency tree B -> A ->
commons-lang. In module B we have dependency:unpack try to unpack commons-lang,
without specifying a version. This will fail with the following error message,
even though the version of this dependency is specified in A.
[INFO] [dependency:unpack {execution: unpack}]
[INFO] Configured Artifact: commons-lang:commons-lang:?:jar
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Unable to find artifact version of commons-lang:commons-lang in either
dependency list or in project's dependency management.
[INFO] ------------------------------------------------------------------------
The attached example should demonstrate this problem (commons-lang chosen for
no particular reason).
