Renaming files during ANT copy

问题:

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, the files are copied (without the renaming)

Thanks for any help. James

<?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"/>
      <mapper>
        <chainedmapper>
          <mapper type="glob" from="*PACKAGENAME*" to="*${package.name}*"/>
          <mapper type="glob" from="*GAMENAME*" to="*${game.name}*"/>
          <mapper type="identity"/>
        </chainedmapper>
      </mapper>
    </copy>
  </target>
</project>

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"/>

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

(quite an old question, but I just found searching for almost the same problem :-))
