Unable to install source or javadoc artifacts in local repository

I couldn't find a way of installing a source archive or a javadoc archive in the local repository. Basically I'm missing the option to specify a classifier when invoking mvn install:install-file. As you can see in the output below it overwrites the main artifact (e.g. xmlc-base-2.2.9.jar)

F:\downloads\xmlc-src-2.2.9\xmlc-src-2.2.9\xmlc\modules\xmlc\src>mvn install:ins
tall-file -Dfile=xmlc-base-2.2.9-sources.jar -DgroupId=org.enhydra.xmlc -Dartifa
ctId=xmlc-base -Dversion=2.2.9 -Dclassifier=sources -Dpackaging=jar

The exact same works when using the deploy plugin to install a source artifact in the remote repository, because that plugin accepts an optional classifier.
