Question

I had a hard time understanding how to install or deploy a jar file with its accompanying sources (or any additional classifier for that matter). The documentation wasn’t clear to me and left me to do some trial and error.

Answer 1

Here is an example of how to use a classifier with maven ant run tasks:

<target name="install-jar">
    ...
    <artifact:pom id="sharedPom" file="shared/pom.xml" />
    <artifact:install file="${classesdir}/shared.jar" >
        <pom refid="sharedPom" />
        <attach file="${builddir}/shared-sources.jar" classifier="sources" />
    </artifact:install>
</target>

The attach referenced to in the documentation is meant to be a sub-element. Hope this helps.
