Deploy jar to "platform/lib" folder

I'm developping a netbeans platform 8.1 application using Maven.

I use a JTattoo look and feel and the only way I found to make it work is to copy the jtattoo jar file to "platform/lib". 

It's ok during the developpment but is it possible to customize the way Netbeans (with Maven) generates the zip and installers to automatically copy one jar file to this directory ?
