如何递归地运行chown ant任务？

Question

我想在recursilvely中更改AIX中目录的所有权。 我用

<osexec commandbase="su" dir="/bin" mode="osexec">
<args>
<arg line="chown -R ${broker_admin_name}:${broker_admin_name} ${broker_installation_directory}/dcx"/>
</osexec>

这段代码是否正确？ 我想在dcx（包括dcx）下更改所有目录和文件的所有权，但我无法通过执行此操作来更改所有权。我也尝试：

<chown owner="${broker_admin_name}">
<fileset dir="${broker_installation_directory}/dcx" includes="**/*">
</fileset>
<dirset dir="${broker_installation_directory}/dcx" includes="**/*">
</dirset>
</chown>

但是只有dcx下的目录才能更改所有权而不是文件。 另外，我可以通过build.xml中的普通shell命令执行此操作吗？ ie chown -R abc:abc xyz如何直接在build.xml中执行此操作？

您是否收到“不允许操作”错误消息？

实施例

在Ubuntu上，chown任务受操作系统的限制：

$ ant

build:
    [chown] chown: changing ownership of `/home/mark/tmp/build/one/test.txt': Operation not permitted
    [chown] chown: changing ownership of `/home/mark/tmp/build/three/test.txt': Operation not permitted
    [chown] chown: changing ownership of `/home/mark/tmp/build/two/test.txt': Operation not permitted
    [chown] chown: changing ownership of `/home/mark/tmp/build': Operation not permitted
    [chown] chown: changing ownership of `/home/mark/tmp/build/one': Operation not permitted
    [chown] chown: changing ownership of `/home/mark/tmp/build/three': Operation not permitted
    [chown] chown: changing ownership of `/home/mark/tmp/build/two': Operation not permitted
    [chown] Result: 1
    [chown] Applied chown to 3 files and 4 directories.

运行“chown”命令演示了相同的限制

$ chown -R an_other_user build
chown: changing ownership of `build/one/test.txt': Operation not permitted
chown: changing ownership of `build/one': Operation not permitted
chown: changing ownership of `build/two/test.txt': Operation not permitted
chown: changing ownership of `build/two': Operation not permitted
chown: changing ownership of `build': Operation not permitted

最佳解决方案是以root用户身份运行ANT：

$ sudo ant

的build.xml

<project name="demo" default="build">

    <target name="init">
        <mkdir dir="build/one"/>
        <mkdir dir="build/two"/>

        <echo file="build/one/test.txt" message="helloworld"/>
        <echo file="build/two/test.txt" message="helloworld"/>
    </target>

    <target name="build" depends="init">
        <chown owner="an_other_user" verbose="true">
            <fileset dir="build"/>
            <dirset dir="build"/>
        </chown>
    </target>

    <target name="clean">
        <delete dir="build"/>
    </target>

</project>
