Failed to deploy artifacts/metadata: No connector available to access repository

Mit Maven 3 werden standardmäßig nur ftp, http und https als Protokoll unterstützt. Andere Protokolle, wie z.B. dav benötigen eine Erweiterung für das jeweilige Protokoll:

<project>
  ...
  <build>
    ...
    <extensions>
      <!-- Enabling the use of WebDAV -->
        <extension>
          <groupId>org.apache.maven.wagon</groupId>
          <artifactId>wagon-webdav-jackrabbit</artifactId>
          <version>2.10</version>
        </extension>
      </extensions>
    ...
  </build>
