[jira] Commented: (MDEP-108) update site to show how to inject custom unarchiver

["Nathan Wells (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MDEP-108?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=214413#action_214413 ] 

Nathan Wells commented on MDEP-108:
-----------------------------------

This is probably not the right forum for this, but I frankly don't know what the right forum is. I would like to add an unarchiver of type "directory" (though I don't know if such a thing exists) to the dependency plugin. 

I could go into more detail, but if you could just point me in the direction of where to post questions like this, I would appreciate it. Google seems to be failing me.

Thanks!

>             Project: Maven 2.x Dependency Plugin
>          Issue Type: Improvement
>          Components: unpack-dependencies
>    Affects Versions: 2.0-alpha-4

> I'have developed a Maven plugin that defines a new packaging type. Produced artifacts with this packaging type, have a "car" extension.
> Modules, that depends on "car" modules must unpack them to use them. To do so, I configure the maven-dependency-plugin like this (note that "cecilia-lib" is the name of the packaging type I've defined):
> <plugin>
>   <artifactId>maven-dependency-plugin</artifactId>
>   <executions>
>     <execution>
>       <id>unpack</id>
>       <phase>process-resources</phase>
>       <goals>
>         <goal>unpack-dependencies</goal>
>       </goals>
>     </execution>
>   </executions>
>   <configuration>
>     <includeTypes>cecilia-lib</includeTypes>
>   </configuration>
> </plugin>
> Here, I get the error : 
> Unknown archiver type
> Embedded error: No such archiver: 'car'.
> After some investigations, I add the following in the plexus/components.xml of my plugin:
> <component>
>   <role>org.codehaus.plexus.archiver.UnArchiver</role>
>   <role-hint>car</role-hint>
>   <!-- there is no implementaion of CarUnArchiver, but ZipUnArchive will do the job -->
>   <implementation>org.codehaus.plexus.archiver.zip.ZipUnArchiver</implementation>
>   <instantiation-strategy>per-lookup</instantiation-strategy>
> </component>
> But I still get the same error.
> If I had somewhere in my plugin the following code:
>   container.lookup( "org.codehaus.plexus.archiver.Archiver", "car");
>   archiverManager.getUnArchiver( "car" )
> It works correctly...
> So I can't figure out why it doesn't work from the dependency plugin.
