How to apply jar patch while creating war file using maven

Question

I have maven project that creates the war file. It includes the all the jars from dependencies.

In my case, some jar we received as a product patch. These jar should be overwrite the existing jars those added from the dependencies.

I have added the below plugin

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.1.1</version>
    <configuration>
        <webResources>
            <resource>
                <directory>../../../product-patch/RT_V1/RT/webapps/cct-swift/WEB-INF/lib</directory>
                <targetPath>/WEB-INF/lib</targetPath>
            </resource>
            <resource>
                <directory>../../../product-patch/Patch-4277</directory>
                <targetPath>/WEB-INF/lib</targetPath>
            </resource>
            <resource>
                <directory>../../../product-patch/Patch-4291</directory>
                <targetPath>/WEB-INF/lib</targetPath>
            </resource>
        </webResources>
    </configuration>
</plugin>

Finally I can see the war generated but it contains the old jar only. I would like to achieve this task by making minimum changes in existing maven pom.xml
