Just fyi, you can define placeholders a la ${my.db.url} in text files
and have these replaced by maven during build time.

So you could do

<build>
  <filters>
    <filter>src/main/filters/${env}.properties</filter>
  </filters>
  <resources>
    <resource>
        ....
        <filtering>true</filtering>
        <includes>**/*.xconf</includes>
    <resource>
  <resources>
</build>

combined with this in settings.xml:

<profile>
  <activation>
  ....
  <properties>
    <env>prod</env>
  </properties>
</profile>

Note that ${env} in the pom is resolved to the <env> property in the
profile.

That way you wouldn't have to duplicate your configuration files.
