Documentation: filter web.xml should recommend to add a pregoal to war:war-resources

Documentation says:

"If you need to copy the web.xml file in order to replace some filter tokens or simply perform some custom modification to it, simply write a pre-goal to the war:war goal in which you perform the manipulation. Then set the maven.war.webxml property to point to your modified web.xml."

instead it could say

[...] simply write a pre-goal to the war:war-resources [...]

Otherwise it won't work with exploded war files.
