Ant and scp

[Angel Dobbs-Sciortino]

I am trying to use the scp task in ant to deploy my web application, but it's not working. I keep getting an exception saying "auth fail". Does anyone know why it's doing this?

Here is my ant task:

<target name="scpwar">
  <scp file="${dir.dist}/attw.war"
    todir="${user}@${host}:/usr/local/tomcat/webapps"
    password="${pass}"
    trust="true"/>
</target>

Here is my stack trace:

Has nobody else here used the scp task?

[Guy Allard]

No I have not, but do use ssh/scp command line quite a bit.

1) Can you run this from the command line?

2) Can you run this outside of ant, using just the jsch.jar?

3) Are all of your ant properties set correctly?

Re: Use of password: you should investigate key authorization.
