Maven resource filtering doesn't work in a SwitchYard (SOA-P 6) project

Issue

• I'm trying to use Maven's resource filtering in my project's pom.xml like this:

    <build>
        ...
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
        </resources>
        ...

• To modify my switchyard.xml below at build time.

         <sca:reference name="routerToFile" promote="FirstServiceESB/FileRouterListener" multiplicity="1..1">
            <file:binding.file>
                <file:directory>${project.build.directory}/output</file:directory>
                <file:autoCreate>true</file:autoCreate>
                <file:fileName>results.log</file:fileName>
            </file:binding.file>
        </sca:reference>

• However, the filtering doesn't happen.
• I'm also using switchyard-plugin in my pom.xml to utilise the bean scanner, and suspect it may be because this plugin takes switchyard.xml away before Maven's filtering it during packaging.
