[jira] Commented: (MNG-2110) ArtifactRepositoryLayout isn't
extensible
[ http://jira.codehaus.org/browse/MNG-2110?page=comments#action_59816 ]
Matthew Beermann commented on MNG-2110:
---------------------------------------
Hm, it won't let me change the name of the issue, but a better summary line might be: "Only certain components are extensible from a plugin". Lifecycles and packaging yes, but repository layouts no? It seems arbitrary.
I can make it work if I put the code directly into MAVEN_HOME\lib, but there's no (obvious) reason it shouldn't work from a <plugin/> with <extensions>true</extensions>.

> I'm writing a plugin that (among other tasks) provides a new ArtifactRepositoryLayout suitable for Eclipse repositories. In my META-INF/plexus/components.xml, I have:
> <component>
> <role>org.apache.maven.artifact.repository.layout.ArtifactRepositoryLayout</role>
> <role-hint>eclipse</role-hint>
> <implementation>org.apache.maven.artifact.repository.layout.EclipseArtifactRepositoryLayout</implementation>
> </component>
> This plugin is listed in the POM with <extensions>true</extensions>. I would expect that a <repository/> with <layout>eclipse</eclipse> would discover and load this layout provider. Instead, it simply results in an exception. Note that this same components.xml file also defines some lifecycle mappings, which work perfectly.
> [INFO] Trace
> org.apache.maven.reactor.MavenExecutionException: Cannot find layout implementation corresponding to: 'eclipse' for remote repository with id: 'Eclipse Update Site'.
