重命名VS移动Ant任务 [英] Rename Vs Move Ant task

问题描述

其实我使用＆LT;移动＆GT; CMD重命名一个文件夹，而不是＆LT;重命名＆GT; CMD。但在我的情况下，我在这里移动48746的文件，所以需要1小时左右。请告诉我蚂蚁适当的方式到该文件夹​​重命名最佳方式。先谢谢了。

 ＆lt;目标名称=rename_folder_jet取决于=Upload_on_ftp＆GT;
    ＆LT;将todir =$ {} build.dir _ _jet $ {} ver_number＆GT;
        ＆LT;文件集DIR =$ {} build.dir＆GT;
            ＆LT;包括姓名= /＆GT** / *。*;
        ＆LT; /文件集＆GT;
    ＆LT; /移动＆GT;
＆LT; /目标与GT;
 

解决方案

尝试移动/只重命名的目录，而不是它的全部内容。像这样的：

 ＆lt;目标名称=rename_folder_jet取决于=Upload_on_ftp＆GT;
    ＆LT;移动文件=$ {} build.dirtodir =$ {} build.dir _ _jet $ {} ver_number/＆GT;
＆LT; /目标与GT;
 

和确保您开始前，目标目录不存在。

我尝试用下面的生成文件：

 ＆LT;项目默认=rename_folder_jet＆GT;
  ＆LT;属性名=build.dirVALUE =构建/＆GT;
  ＆LT;属性名=ver_numberVALUE =0.3/＆GT;  ＆lt;目标名称=设置＆GT;
    ＆LT; MKDIR DIR =$ {} build.dir/＆GT;
    ＆LT; MKDIR DIR =$ {} build.dir /富/＆GT;
    ＆LT; MKDIR DIR =$ {} build.dir /酒吧/＆GT;
  ＆LT; /目标与GT;  ＆lt;目标名称=拆解＆GT;
    ＆LT;删除DIR =$ {} build.dir _ _jet $ {} ver_number/＆GT;
  ＆LT; /目标与GT;  ＆lt;目标名称=rename_folder_jet＆GT;
    ＆LT;移动文件=$ {} build.dirtodir =$ {} build.dir _ _jet $ {} ver_number/＆GT;
  ＆LT; /目标与GT;
＆LT; /项目＆GT;
 

在调试（蚂蚁-d）与上述执行Ant是有趣的。

案例1：

 蚂蚁拆机
蚂蚁设置
蚂蚁-d
 

在这种情况下，移动/重命名的目标目录不存在。蚂蚁的调试输出显示：

  [移动]试图重命名目录：C：\\用户\\须藤code \\ tmp目录\\蚂蚁\\建到C：\\用户\\须藤code \\ tmp目录\\蚂蚁\\ build_jet_0.3 \\构建
 

案例2：

 蚂蚁设置
蚂蚁
蚂蚁设置
蚂蚁-d
 

在此情况下，目标目录已经存在于第二执行。蚂蚁的调试输出显示：

  [移动]试图重命名目录：C：\\用户\\须藤code \\ tmp目录\\蚂蚁\\建到C：\\用户\\须藤code \\ tmp目录\\蚂蚁\\ build_jet_0.3 \\构建
文件集：在DIR C安装扫描仪：\\用户\\须藤code \\ tmp目录\\蚂蚁\\建立与patternSet {包括：[]不包括：[]}
     [举措]删除目录c：\\用户\\须藤code \\ tmp目录\\蚂蚁\\编译\\富
     [举措]删除目录c：\\用户\\须藤code \\ tmp目录\\蚂蚁\\编译\\酒吧
     [举措]删除目录c：\\用户\\须藤code \\ tmp目录\\蚂蚁\\构建
 

如此看来，如果目标目录不存在，蚂蚁会做的改名的目录。但如果目标目录存在，它，而不是做了的复制的进入目录，并从源目录，而不是删除。

Actually i am using <move> cmd for renaming one folder instead of <rename> cmd. but in my case i am moving here 48746 files, so takes 1 approx hour. pls tell me ant appropriate way to rename that folder in optimal way. Thanks in advance.

<target name="rename_folder_jet" depends="Upload_on_ftp">
    <move todir="${build.dir}_jet_${ver_number}">
        <fileset dir="${build.dir}">
            <include name="**/*.*"/>
        </fileset>
    </move>
</target>

解决方案

Try to move/rename the directory only, rather than all its contents. Like this:

<target name="rename_folder_jet" depends="Upload_on_ftp">
    <move file="${build.dir}" todir="${build.dir}_jet_${ver_number}"/>
</target>

And make sure that the target directory does not exist before you start.

I experimented with the following build file:

<project default="rename_folder_jet">
  <property name="build.dir" value="build"/>
  <property name="ver_number" value="0.3"/>

  <target name="setup">
    <mkdir dir="${build.dir}"/>
    <mkdir dir="${build.dir}/foo"/>
    <mkdir dir="${build.dir}/bar"/>
  </target>

  <target name="teardown">
    <delete dir="${build.dir}_jet_${ver_number}"/>
  </target>

  <target name="rename_folder_jet">
    <move file="${build.dir}" todir="${build.dir}_jet_${ver_number}"/>
  </target>
</project>

Executing Ant in debug (ant -d) with the above is interesting.

Case 1:

ant teardown
ant setup
ant -d

In this case, the target directory of the move/rename does not exist. The debug output of Ant shows:

 [move] Attempting to rename dir: C:\Users\sudocode\tmp\ant\build to C:\Users\sudocode\tmp\ant\build_jet_0.3\build

Case 2:

ant setup
ant
ant setup
ant -d

In this case, the target directory exists already on the second execution. The debug output of Ant shows:

     [move] Attempting to rename dir: C:\Users\sudocode\tmp\ant\build to C:\Users\sudocode\tmp\ant\build_jet_0.3\build
fileset: Setup scanner in dir C:\Users\sudocode\tmp\ant\build with patternSet{ includes: [] excludes: [] }
     [move] Deleting directory C:\Users\sudocode\tmp\ant\build\foo
     [move] Deleting directory C:\Users\sudocode\tmp\ant\build\bar
     [move] Deleting directory C:\Users\sudocode\tmp\ant\build

So it seems that if the target directory does not already exist, Ant will do a rename of the directory. But if the target directory exists, it instead does a copy into the directory and delete from the source directory instead.
