min yun law commented on SSHD-1106:
-----------------------------------
trace the Mina sshd code, the scp command string is from :
String cmd = ScpClient.createReceiveCommand(remote, Collections.emptyList());
which return something like: "-p -f – remotefilefullpath"
and in AbstractScpClient.java
protected ChannelExec openCommandChannel(ClientSession session, String cmd)
throws IOException {
long waitTimeout = session.getLongProperty(SCP_EXEC_CHANNEL_OPEN_TIMEOUT,
DEFAULT_EXEC_CHANNEL_OPEN_TIMEOUT);
ChannelExec channel = session.createExecChannel(cmd);
...
this channel has problem to parse the scp cmd if the remote filename has
space(since it is invalid)
so, when call those ScpClient.upload() and download() API, we have to quote
the remote file name, but these API has no comment to describe this limitation.
> SCP failed for target filename with space inside

> String remotePath = "/tmp";
> File localPathFile = new File(localDir, fileName);
> Path pathFile = localPathFile.toPath();
> //remote is linux
> String remoteFullPath = remotePath+"/"+fileName;
> Collection<ScpClient.Option> options = EnumSet.noneOf(
> ScpClient.Option.class);
