[jira] Commented: (WAGONSSH-55) Although a password is given in the settings.xml for a scp url, a password prompt still appears

Juan F. Codagnone commented on WAGONSSH-55:
-------------------------------------------

The server is sending "keyboard-interactive", not "password" or "key" so the server could ask for a question different that the user/password ("PasswordAuthentication no" in sshd_config?).  See WAGONSSH-13. 

I think that the real solution would be to have an agent to store the credentials.

> I want to deploy an artifact on a remote repository using scp (not scpexe) by issuing the command mvn deploy. In the settings.xml, I have specified an username and the correct password for the user, and I made sure that the settings file is read by maven. Still, wagon prompts me for a password when establishing the ssh connection for every ssh access (6 times for deploying a plugin). If I enter the correct password 6 times, deployment works but typing the password so often is very tedious.
> I tried to look into the code and although I am not familiar with ssh and jsch, it appears to me that the problem occurs if the ssh server sends back the authentication method should be "keyboard-interactive" (see jsch's Session.connect(int) method). Then Jsch does not use the provided password but tries to prompt it from console. This ends up in Wagon's UserInfoUIKeyboardInteractiveProxy.promptKeybordInteractive() method.
> If I replace the code in the method promptKeyboardInteractive, which was originally
>         return interactive.promptKeyboardInteractive( destination, name, instruction, prompt, echo );
> by
>         String[] result = new String[prompt.length];
>         result[0] = userInfo.getPassword();
>         return result;
> (which is a bad hack in my opinion), then the authentication works without having to type in the password. I did not dig deep enough into the wagon code to see if there is a clean way to solve this, but perhaps somebody else has an idea.
> I'd be happy to test any other solutions if it is difficult to reproduce the problem on another Linux Sytem.
