install:install should remove leftovers from local repository
-------------------------------------------------------------
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)
