Can Maven re-sign dependencies?

I'm using maven-jarsigner-plugin to sign a shaded uber-jar of mine. I do need to distribute some dependencies in their own jars though, and want to take those jars from a Maven repo, clear them of any existing signatures, and sign them with my own certificate.

Are there any Maven plugins that do this, or would i involve some Ant plugin hackery?

Turns out maven-jarsigner-plugin can re-sign existing jars using it's removeExistingSignatures config element. So simple!

I use maven-dependency-plugin to copy artifacts into a .war project in the generate-resources phase, then sign them in the process-resources phase.
