<includes> and <excludes> do not seem to work correctly during scm:checkin

I am trying to use the scm plugin automatically during Maven builds. My real goal for this is to check only one file back in, but no matter what I try, the plugin checks in ANY file that has been changed. Below is one configuration that I have tried.

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-scm-plugin</artifactId>
<version>1.0</version>
<inherited>false</inherited>
<executions>
<execution>
<phase>process-resources</phase>
<goals>
<goal>checkin</goal>
</goals>
<configuration>
<excludes>*/*</excludes>
<includes>version.properties</includes>
</configuration>
</execution>
</executions>
</plugin>

I also tried using only the <includes> tag without excluding anything, but it did not work either.
