How to disable “Test Source Xref” report generation

[Aleksandra Nowak]

Hi all!
I'm using Maven Site Plugin to generate my project page and the JXR Plugin
to publish the source code. But I don't want to publish sources of test
classes. Does anybody know if it is possible to disable "Test Source Xref"
report. I've only found this pagehttp://jira.codehaus.org/browse/JXR-47 but
this parameter doesn't seem to work. My configuration in POM looks like
this:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-site-plugin</artifactId>
<version>3.2</version>
<configuration>
<reportPlugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jxr-plugin</artifactId>
        <version>2.3</version>
        <configuration>
            <suppressTestXref>true</suppressTestXref>
        </configuration>
    </plugin>
</reportPlugins>
</configuration>
</plugin>

Kind regards,
Alex
