I'm using the FTP Ant task with maven-antrun-plugin

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <executions>
        <execution>
            <id>ftp</id>
            <phase>generate-resources</phase>
            <configuration>
                <tasks>
                    <ftp action="get"
                         server="${ftp.server.ip}"
                         userid="${ftp.server.userid}"
                         password="${ftp.server.password}"
                         remotedir="${ftp.server.remotedir}"
                         depends="yes" verbose="yes"
                         skipFailedTransfers="true"
                         ignoreNoncriticalErrors="true">
                        <fileset dir="target/test-classes/testdata">
                            <include name="**/*.html" />
                        </fileset>
                    </ftp>
                </tasks>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
...

the problem is that my build fails when the folder ${ftp.server.remotedir} doesn't exist.
I tried to specify

skipFailedTransfers="true"
ignoreNoncriticalErrors="true

but these don't fix the problem and the build keeps failing.

An Ant BuildException has occured: could not change remote directory: 550 /myBadDir: The system cannot find the file specified.

Do you know how to instruct my maven build to don't care about this Ant task error
