--------------------------------

    Resolution: Won't Fix

> install:install should remove leftovers from local repository

>                 Key: MANTRUN-153
>                 URL: http://jira.codehaus.org/browse/MANTRUN-153
>             Project: Maven 2.x Antrun Plugin
>          Issue Type: Bug
>    Affects Versions: 1.5
>            Reporter: Petr Kozelka
>         Attachments: pom.xml
>
>
> It happens that we need to change the set of output artifacts. When this 
> happens, the install mojo does not bother to remove older artifacts that are 
> no longer produced by this module.
> The bad effect is, that other modules depending on the obsolete artifacts can 
> still use it. Much better behavior in this situation would be, to remove the 
> obsolete files from the local repository's directory dedicated for given 
> module.
> h4. reproducing the problem
> # download the sample pom to an empty directory
> # execute {{mvn clean install -Dc=obsolete-demo}} - this represents the 
> "older version" of a module
> # execute {{mvn clean install}} - this represents the "newer version" of a 
> module, after changing the classifier
> # now, look in the local repo using {{ls -1 
> $HOME/.m2/repository/demo/sample-zip-module/1-SNAPSHOT}} - you will see this:
> {quote}
> maven-metadata-local.xml
> sample-zip-module-1-SNAPSHOT-demo.zip
> {color:red}sample-zip-module-1-SNAPSHOT-obsolete-demo.zip{color}
> sample-zip-module-1-SNAPSHOT.pom
> {quote}
> h4. possible solutions
> I see two approaches
> # *drop the installdir first* - straightforward
> # *list installdir, install, drop leftovers* - slightly more complicated but 
> maximizes the time of installed module existence
