How to remove existing and add new updated header

[dhoffer]

We have our POMs configured to add/set a header with the format goal and hour license is configured via:

<licenseSet> <header>${main.basedir}/src/license/license.txt</header> </licenseSet>

This worked fine for the initial header/license but now that we need to update the header/license the format goal does not replace the prior header it adds a new one instead.

I then thought I would use the remove goal to remove the older header and then add the new one with the format goal. However this does not work, the remove goal does nothing. The old header still exists.

How can I update my header/license with this plugin?
