If you are working in a large group of developers, you'll want to make sure that your web site's files end up with the proper user and group permissions after they are published to the remote server. To configure specific file and directory modes for use during the site deployment, include the following in $HOME/.m2/settings.xml:

<settings>
  ...
  <servers>
    ...
    <server>
      <id>hello-world.website</id>
      ...
      <directoryPermissions>0775</directoryPermissions>
      <filePermissions>0664</filePermissions>
    </server>
  </servers>
  ...
</settings>

The above settings will make any directories readable and writable by either the owner or members of the owner's primary group; the anonymous users will only have access to read and list the directory. Similarly, the owner or members of the owner's primary group will have access to read and write any files, with the rest of the world restricted to read-only access.
