Ignore file not found at any time

[svrolanski]

I'm using this plugin to copy configurations files (quartz, hibernate, ehcache, ...) to specific environment (production, testing, ...) to their expected names ("hibernate.cfg.production.xml to hibernate.cfg.xml"). Sometimes the configuration file does not exist, because all environment share the same configuration, so I keep a single file for easier management. When the file doesn't exist the build stops with an error. Could you add an option to ignore file not found errors at any time instead of just during incremental build?
