I\'d like to copy a directory of files, and rename some of them in the process. When I run the script below, nothing copies. If I comment the glob mappers in the file below,
Your problem is that you did not choose the right mapper: <chainedmapper>  will pass information in chain from the first to the last mapper
Instead, <firstmatchmapper> should be used, which will try all mappers in turn, until one matches
Reference: http://ant.apache.org/manual/Types/mapper.html
(quite an old question, but I just found searching for almost the same problem :-))
Resorted to a workaround, using "move", and the correct mapper type as indicated by Mnementh. Thanks
<?xml version="1.0" ?>
<project name="Create project structure" default="main">
    <target name="main" description="Copy template files to project folder">
    <echo>Copying template files to project folder</echo>
    <copy todir="${project.dir}" verbose="true" overwrite="true">
        <fileset dir="${shared.files}/templateproject" excludes=".svn" />
    </copy>
    <move todir="${project.dir}">
        <fileset dir="${project.dir}" />
        <mapper>
        <mapper type="regexp"
                from="(.*)PACKAGENAME(.*)" to="\1${package.name}\2" />
        <mapper type="regexp"
                from="(.*)GAMENAME(.*)" to="\1${game.name}\2" />
        </mapper>
    </move>
    </target>
</project>
It seems, that the glob-mapper works only with one '*'. I would try the regexp-mapper:
<mapper type="regexp" from="(.*)PACKAGENAME(.*)" to="\1${package.name}\2"/>
<mapper type="regexp" from="(.*)GAMENAME(.*)" to="\1${game.name}\2"/>
