Ant: scp create directory if not exist

Question

I am using this to copy from A to B. But if for example the folder /config doesnt exist it gives me an exception. How can I solve it? I tried mkdirs="true" but it runs to error as well

<scp todir="${ftplogin}@${ftpserver}:${ftp-remote-dir}/config" verbose="false" trust="true" failonerror="No">
            <fileset dir="${stuff}/${stuff-version}/config${config-files}">
                <include name="*.*"/>               
            </fileset> 
        </scp>

Answer 1

You can use sshexec to create directories tree on remote machine before coping. mkdir -p creates directories if not exists. (How to mkdir only if a dir does not already exist?)

<sshexec
    host="${host}"
    username="${remote_user}"
    password="${remote_password}"
    command="mkdir -p ${remote_dir_path}"
    trust="true" />

Add it to your target before scp

Answer 2

It's not possible to create remote directories with scp task. Here's a macrodef for scptransfer, that does all the work needed for transfer from a given stagedirectory => fix linefeeds, createremote, deleteremote, fail if stagedir empty ... etc. Macrodef is using ant addon Flaka, if you don't need all that bells and whistles, simply use sshexec task with mkdir -p before scp to create your remote targetdir.
