In your pom, within the <build> node, you'll need to enable filtering like this:

<build>
    <resources>
        <resource>
            <directory>assets</directory>
            <filtering>true</filtering>
            <includes>
                <include>**/*.properties</include>
            </includes>
        </resource>
        <resource>
            <directory>assets</directory>
            <filtering>false</filtering>
            <excludes>
                <exclude>**/*.properties</exclude>
            </excludes>
        </resource>
    </resources>

    ...

</build>

Once that's done, you can test by running:

mvn resources:resource -Durl=http://www.test.com/

Note that the excludes portion is there because you don't want Maven to filter through any binary files that you may have in the assets directory. If you don't have that portion, it usually ends up corrupting any binary files by attempting to filter them.

With the way that this is configured, the filtered property file will go into target/classes, which you probably don't want. You can change that by adding a <targetPath> node. See this link for more notes on configuring resources.
