   <faq id="question">
     <question>I get an Unsupported Protocol Error when deploying a 3rd party jar. What should I do?</question>
     <answer>
       <p>
         If you are using the <code>deploy:deploy-file</code> goal and encounter
         this error:
       </p>
       <p>
         <i>"Error deploying artifact: Unsupported Protocol: 'ftp': Cannot find
         wagon which supports the requested protocol: ftp"</i>
       </p>
       <p>
         Then you need to place the appropriate wagon provider in your
         <code>%M2_HOME%/lib</code>. In this case the provider needed is ftp,
         so we have to place the wagon-ftp jar in the lib directory of your
         Maven 2 installation.
       </p>
       <p>
         As an alternative to placing the wagon provider into the Maven distribution, you can also create a dummy
         POM that declares the required wagon as an <code>&lt;extension&gt;</code> inside the current directory.
       </p>
       <p>
         If the error description is something like this:
       </p>
       <p>
         <i>"Error deploying artifact: Unsupported Protocol: 'ftp': Cannot find
         wagon which supports the requested protocol: ftp
         org/apache/commons/net/ftp/FTP"</i>
       </p>
       <p>
         Then you need to place the commons-net jar in
         <code>%M2_HOME%/lib</code>.
       </p>

     <faq id="skip">
       <question>I don't want to deploy one of the artifacts in my multi-module build.  Can I skip deployment?</question>
       <answer>
         <p>
           Yes, you can skip deployment of individual modules by configuring the Deploy Plugin as follows:
         </p>
         <source>
<![CDATA[<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-deploy-plugin</artifactId>
  <version>X.Y</version>
  <configuration>
    <skip>true</skip>
  </configuration>
</plugin>]]></source>
       </answer>
     </faq>
     <faq id="deploy_deploy">
       <question>What does the message "The packaging for this project did not assign a file to the build artifact" mean when I run <code>deploy:deploy</code>?</question>
       <answer>
         <p>
         During the packaging-phase all gathered and placed in context. 
         With this mechanism Maven can ensure that the <code>maven-install-plugin</code> and <code>maven-deploy-plugin</code> are copying/uploading the same set of files.
         So when you only execute <code>deploy:deploy</code>, then there are no files put in the context and there is nothing to deploy.
