[jira] Closed: (MNG-4451) Parametized declarations fail
in two level deep multi-module project
[ http://jira.codehaus.org/browse/MNG-4451?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Benjamin Bentmann closed MNG-4451.
----------------------------------
Resolution: Won't Fix
Assignee: Benjamin Bentmann
Thanks for the example project Julien. And yes, using expressions for the project coordinates is not going to be supported (cf. MNG-4297).
> Parametized <groupId/> declarations fail in two level deep multi-module project
> -------------------------------------------------------------------------------
>
> Key: MNG-4451
> URL: http://jira.codehaus.org/browse/MNG-4451
> Project: Maven 2 & 3
> Issue Type: Bug
> Components: Bootstrap & Build
> Affects Versions: 2.2.1
> Environment: Windows XP, JDK 1.6.0_16
> Reporter: J. Michael McGarr
> Assignee: Benjamin Bentmann
> Attachments: MNG-4451.zip

> We utilized the appfuse 2.x multi-module project setup where the modules of the project declare their own <groupId/> value as:
> {quote}
> <groupId>$[pom.parent.groupId].$[pom.parent.artifactId]</groupId>
> {quote}
> (note: replaced the curly braces with brackets due to a wiki error)
> When you add a second level of modules, this approach does not seem to work in Maven. The second level child module, which declares it parent to be a first level child module. It appears that the parameter declaration in the first-level module is ambiguous or is resolving to value as seen by the second-level module. This can be seen below in the output of the error the Maven reactor provides.
> I was able to work around this error by changing the parametized groupId declaration in the first-level module pom and making it explicit. If there is something wrong with this approach or another parametized setting I need to use, please let me know.
