static root folder for maven projects

Static files could be copied here:
<maven-project-root>\src\main\webapp\resources

They are accessed on server on URL:
<server_address>/resources

Example:
<maven-project-root>\src\main\webapp\resources\x.txt
could be accessed on
http://localhost:8080/resources/x.txt

In come cases, the content changes are actualized without server restart. For example with:
mvn jetty:run
