Fix Version/s: 4.23.0
Resolution: Fixed
> camel-file: a file endpoint whose directory is an existing regular file
> starts and stays silent; fail with a message (and flag it in camel validate)

> Key: CAMEL-24839
> URL: https://issues.apache.org/jira/browse/CAMEL-24839
> Project: Camel
> Issue Type: Improvement
> Components: camel-file, camel-jbang
> Reporter: Claus Ibsen
> Priority: Major
> Fix For: 4.23.0
>
>
> A route that names a file where the file component expects a directory starts
> without a word and never delivers anything:
> {code:yaml}
> - route:
> from:
> uri: "file:order.json?noop=true"
> steps:
> - log: "READ ${header.CamelFileName}"
> {code}
> {{Started route1 (file://order.json)}} and then silence. The same with
> {{pollEnrich}} on {{file://.//order.json}}: the body comes back null after
> the timeout. {{order.json}} exists next to the route as a regular file, so
> the consumer polls a "directory" that is a file and finds no entries.
> Two improvements:
> # At startup (or on the first poll), when the configured directory exists and
> is a regular file, fail with a message that says what to write: "order.json
> is a file, not a directory: to read one file use file:.?fileName=order.json
> (or poll it with pollEnrich)". Today the check in
> {{FileConsumer.pollDirectory}} only logs at DEBUG that the directory does not
> exist or is not a directory, and {{directoryMustExist}} is off by default.
> # {{camel validate yaml}} sees the project directory, so it can flag a file:
> endpoint (in from:, to:, poll: or pollEnrich) whose directory part is an
> existing regular file, with the same hint.
> Found in the round-2 local-model benchmark on the camel-jbang-examples ladder
> (json-transform): the model wanted to read order.json next to the route,
> wrote the file name as the endpoint path, and got no output and no message
> for two attempts. A person new to the file component writes exactly this.
