Deployment of artifacts with FTP

In order to deploy artifacts using FTP you must first specify the use of an FTP server in the distributionManagement element of your POM as well as specifying an extension in your build element which will pull in the FTP artifacts required to deploy with FTP:

<project>
  <parent>
    <groupId>com.stchome</groupId>
    <artifactId>mavenFull</artifactId>
    <version>1.0</version>
  </parent>
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mycompany</groupId>
  <artifactId>my-app</artifactId>
  <packaging>jar</packaging>
  <version>1.1-SNAPSHOT</version>
  <name>Maven Quick Start Archetype</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>

  <!-- Enabling the use of FTP -->
  <distributionManagement>
    <repository>
    <id>ftp-repository</id>
    <url>ftp://repository.mycompany.com/repository</url>
    </repository>
  </distributionManagement>

  <build>
    <extensions>
      <extension>
        <groupId>org.apache.maven.wagon</groupId>
         <artifactId>wagon-ftp</artifactId>
         <version>1.0-alpha-6</version>
      </extension>
    </extensions>
  </build>

</project>

Your settings.xml would contain a server element where the id of that element matches id of the FTP repository specified in the POM above:

<settings>

  ...

  <servers>
    <server>
      <id>ftp-repository</id>
      <username>user</username>
      <password>pass</password>
    </server>

  </servers>

  ...

</settings>

You should, of course, make sure that you can login into the specified FTP server by hand before attempting the deployment with Maven. Once you have verified that everything is setup correctly you can now deploy your artifacts using Maven:

mvn deploy
