[[jetty-maven-scanning]]
=== Files Scanned by the Jetty Maven Plugin

If you set a non zero `scanInterval` link:#jetty-maven-plugin[configuration parameter], the `jetty-maven-plugin` will scan certain files every `scanInterval` seconds for changes, and redeploy the webapp if necessary.
The files that are scanned depend on the goal being executed.
