Maven War Plugin: Copy webResources after resources - maven

Question

I am using the maven-war-plugin to copy the webapp resources and a few external resources to the target directory and then build the war file.
Here is the plugin configuration,
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.2</version>
<configuration>
<!-- Importing React App which is not in the build path -->
<webResources>
<resource>
<directory>react/build</directory>
<targetPath>ui/build</targetPath>
</resource>
</webResources>
</configuration>
<executions>
<execution>
<id>default-war</id>
<phase>package</phase>
<goals>
<goal>war</goal>
</goals>
</execution>
</executions>
</plugin>
This configuration works well, but the external resources (webResources) are copied first and then the build path content is copied.
Build steps,
Copy external resources (webResources)
Copy resources from build path (warSourceDirectory)
Build War file.
This is an extract from the maven build logs,
[INFO] --- maven-war-plugin:2.2:war (default-war) # ReactProject ---
...
[INFO] Copying webapp webResources [...\react\build] to [...\target\ReactProject-0.0.1]
[DEBUG] + \ui\build\app.js has been copied.
...
[INFO] Copying webapp resources [...\ReactProject\src\main\webapp]
[DEBUG] + \ui\html\index.html has been copied.
...
[INFO] Building war: ...\ReactProject\target\ReactProject-0.0.1.war
Due to this behavior if similar content is present in the build path it overwrites the content copied from the react folder. Also, it would be more intuitive if the external content is copied after the build path resources are configured.
Is there a way to configure the webResources to be copied after the main resources?
