Solved! I didn't find anything built in, so I did the following:
1. Add a custom Producer based on the File producer, that overrides
createFileName to add a suffix when the file is a duplicate:
class ArchiveProducer(endpoint: GenericFileEndpoint[File], operations:
GenericFileOperations[File])
extends GenericFileProducer[File](endpoint, operations) {
2. Add a custom endpoint that overrides createProducer to return my custom
producer:
class ArchiveEndpoint(uri: String, component: Component) extends
FileEndpoint(uri, component) {
3. Add a custom component that creates my custom endpoint, by overriding
buildFileEndpoint:
class ArchiveComponent extends FileComponent {
4. Register my custom component when setting-up Camel:
camelContext = CamelContextBuilder()
camelContext.addComponent("archive", new ArchiveComponent())
5. Change my file:// URIs to archive:// URIs to use my new component.
