sorry for delay.

one example is the openshift project.

https://github.com/jbosstools/jbosstools-openshift/blob/jbosstools-4.2.0.Beta3x/plugins/org.jboss.tools.openshift.express.client/pom.xml#L32

shows how we define copy dependencies.

When you import it as a maven project you'll get errors/warnings about 
"plugin not covered by lifecycle" for tycho related plugins.

Run Quickfix and download the m2e-tycho plugin.

restart eclipse.

now when you maven update the copy goal should be taking into account.
