.gitignore file is not copied to archetype JAR

In the file src/main/resources/META-INF/maven/archetype-metadata.xml, I have something like this:

    ...
    <fileSets>
        <fileSet filtered="false" packaged="false">
            <directory/>
            <includes>
                <include>.*ignore</include>
            </includes>
        </fileSet>
    </fileSets>
    ...

In the directory src/main/resources/archetype-resources, there are two files .gitignore and .hgignore. Now when I create the archetype from the resources, only the .hgignore file gets copied into the archetype, but not the .gitignore file.
