Add Copyright header to all project files (.java, .xml, ...)

Question

I have several maven projects where I'd like to add a common header (copyright information, etc.). Is there a tool, or Eclipse plugin, to do this?

A simple shell script won't do the job, because some files already have such a header - and I don't just want to blindly append another header.

So some plugin with "sophisticated" logic would be appreciated ;-)

Answer 1

If your project supports Maven, you can use maven-license-plugin

There are instructions how to install and use it.
