     <question>Unsupported Protocol Error when deploying a 3rd party jar. What should I do?</question>
     <answer>
       <p>
            When using deploy-deploy-file goal and encountered this error
       </p>
       <p>
            "Error deploying artifact: Unsupported Protocol: 'ftp': Cannot find wagon which supports the requested protocol: ftp"
       </p>
       <p>
            You only have to place the appropriate wagon provider to your %M2_HOME%/lib.
            In this case the provider needed is ftp, so we have to place the wagon-ftp jar to the lib of your m2 installation.
       </p>

            If the error description is something like
       </p>

            org/apache/commons/net/ftp/FTP"
       </p>
       <p>
            Place also the commons-net jar to %M2_HOME%/lib.
