[I] ScpClient download fails silently when the remote files does not exist [mina-sshd]
RyanLivingston opened a new issue, #428:
URL: https://github.com/apache/mina-sshd/issues/428
### Version
2.11.0
### Bug description
When calling `ScpClient(String, String)`, the method does not throw any exception or indicate to the caller that the SCP failed when the remote file is not available. Is this the expected behavior?
From the logging, we can see a WARNING exit status is received but it is only logged.
Is the expectation here to override the client and handle this warning as the client? Or is it expected that I check the filesystem to determine a status?
### Actual behavior
To the client, the API `ScpClient(String, String)` behaves no differently if the remote file exists or does not exist.
### Expected behavior
Some API level indication that the download has failed.
### Relevant log output

Thanks for the response!
This testing is being done on macOS (JDK 18) with what I believe is an _OpenSSH_ server. The testing user has no explicit `~/.ssh/ssh_config` defined and I am connecting locally (I am seeing this issue on other Linux systems).
The test I am running is:

lgoldstein commented on issue #428:
URL: https://github.com/apache/mina-sshd/issues/428#issuecomment-1805470166
Here is the problem: the OpenSSH server defines the missing file a WARNING (status=1) rather than an ERROR (status=2):
>> receive(ScpHelper[ClientSessionImpl[lgoldstein@localhost/127.0.0.1:5252]]) ack=1: scp: 1234.txt: No such file or directory
Therefore the code is correct in not treating this as an error. In order to allow user code to handle this otherwise, we will add a **new** method to the listener to enable user to reach their own decision. **Caveat emptor:** due to the way the code is written we can only provide the **raw** command that caused the error/warning and let the user decide whether to throw an exception or not.

Thanks for the information - I will try and take a look at it when I have some free time (not sure when it will be...)

The log is very long and convoluted - can you show what you mean by

Thank you for the clarification - this sounds very strange - will need to look into it, though there is one more question - what **server** are you using ? Is it *OpenSSH*, MINA SSHD itself or something else ?. FYI, in SCP, the **server** decides on the severity of an error. Our code simply reflects this severity by logging WARNING(s) and throwing exceptions only if server signalled one. Perhaps this is some non-standard implementation of the SCP protocol, or perhaps some non-standard configuration.

Another question - I see that the command being executed is
```
scp -f -- /Users/ryanlivingston/tmp/null.txt
```
What does the "--" stand for ? I am not familiar with this option - usually we copy */some/file1* to */some/file/2*

ScpClient upload also fails silently for permission denied. Is issue 428 here the same issue as https://github.com/apache/mina-sshd/issues/392?

I am not sure how that option was generated in the command string. I do not believe I explicelty set that.

Apologies for including the entire log. After calling `download` with a non-existent remote file path the log prints a warning related to the exit status being of state "warning".
