Description

Some developers would like to keep a JVM running with Camel and then be able to edit a xml file with <camelContext> or <routes> and then have a file watcher automatic detect the file change and reload the routes.

We can have some kind of functionality of that in camel-core for 3rd party to hook into. And then add it to mvn camel:run for some apps where you can quickly bootup a Camel JVM and then scan for file changes with reload.

Mind that this will only work for Camel routes as its not for spring <bean> or OSGi <blueprint> etc as they have their own deployment model. But with the 3rd party hooks, then this may be a way of triggering mvn camel:run to trigger a osgi blueprint reload also when it runs in pojosr mode. Or a spring boot live reload etc.
