>                 Key: MINSTALL-78
>                 URL: http://jira.codehaus.org/browse/MINSTALL-78
>             Project: Maven 2.x Install Plugin
>          Issue Type: Bug
>          Components: install:install
>    Affects Versions: 2.3.1
>            Reporter: Petr Kozelka
>         Attachments: pom.xml

> It sometimes 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 - and later there comes a surprise.
> 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 (if that matters)
