通过命令行参数蚂蚁 [英] passing command line arguments to ant

问题描述

我在蚂蚁比较新的，在学校里我有一个任务做一个build文件。我的一个问题是复制到/ foldercopy的名字（或路径）作为论据蚂蚁的文件。我需要做的是这样的：

I am relatively new in ant, at school I have an assignment to do a build file. One of my questions is to copy to "/foldercopy" the file whose name(or path) is taken as argument for ant. I need to do something like:

蚂蚁cpfile file.txt的

ant cpfile file.txt

所以，蚂蚁将复制到file.txt文件/ foldercopy。我搜索了很多关于谷歌，但我能找到的东西是用-Darg，但我的老师说，这是不正确的。有没有办法做到这一点？

So ant will copy the file.txt to /foldercopy. I searched a lot on google but all I could find was something with "-Darg", but my teacher said that it's not correct. Is there any way to do it?

推荐答案

普通的命令行参数蚂蚁被认为是目标名称，所以如果你想传递参数你的目标，你需要使用属性，通过 -D ：

Plain command line arguments to ant are considered to be target names, so if you want to pass arguments to your target you need to use properties, via -D:

ant -Dfile=file.txt cpfile

和访问值 $ {文件} 里面的build.xml

and access the value as ${file} inside build.xml
