Maven goal / plugin to touch a file

I'm looking for a way to touch a file using maven. The specific user case for this is touching a .reload file in order to force Glassfish to redeploy an Application.

Is there any built-in functionality or plugin able to touch a file?

These possibilities come to mind:

• Use the antrun plugin and the <touch> task
• Use the GMaven plugin and touch the file programmatically using Groovy
