Subject Error with pscp on Windows: "Cannot create file"
Date Wed, 22 Oct 2008 10:10:06 GMT

Hi there, 

I'm trying for some time now to get Maven to work with a Repository accessed
by SSH / SCP. I work with a Windows box and have the putty programs (putty,
plink, pscp, ...) installed and ready in the PATH. I have added the
following <server> configuration to my settings.xml: 
I have pageant running and managing my private key to access the repository.
When I run "mvn package" and the dependencies should be got, I see the
following in my console: 
[WARNING] repository metadata for: '<ARTIFACT>' could not be retrieved from
repository: <REPOSITORY> due to an error: Exit code: 1 - Looking up host

I have masked everything in the above log output that makes it possible to
know who I am working with. I am an external consultant and don't want to
break my contract. :)

It seems to me, that I am successfully accessing the repository (btw. I get
some of the other files I need, so I think it works in principle), but that
I have an error writing the file to my local disk. I have tried to do this
with pscp on the console, and it works just fine. 

Can you tell me how I can make Wagon print me the concrete statement that it
used to copy the file? Or do you perhaps already know what error I'm running

Thank you very much for your help!
