在 Ant 中，如何在文件名中指定带逗号的文件? [英] In Ant, how do I specify files with comma in filename?

问题描述

这是我尝试过的示例目标.事实证明，它想删除所有内容，因为逗号分隔了**/*"和cover"——可以理解.

Here is an example-target that I tried. Turns out, it wants to delete everything because the comma separates "**/*" and "cover" -- understandable.

<target name="clean">
    <delete
        verbose="true">
        <fileset dir="." includes="**/*.pyo"></fileset>
        <fileset dir="." includes="**/*,cover"></fileset>
    </delete>
</target>

如何指定嵌入的逗号?

我正在尝试学习 Ant，这样我就不必为不同的操作系统维护不同的构建系统.在这种情况下，它在 Python 环境中，其中 *,cover 文件由名为 Coverage 的代码覆盖率检查工具创建.

I'm trying to learn Ant so I won't have to maintain different build-systems for different operating-systems. In this case, it's in a Python environment, where *,cover files are created by a code-coverage checking tool called Coverage.

推荐答案

你不需要逃避这个.只需使用 而不是 includes 参数.试试这个:

You don't need to escape this. Just use <include/> instead of includes arg. Try this:

<project name="test" default="clean">

    <dirname property="build.dir" file="${ant.file.test}" />

    <target name="clean">
        <delete>
            <fileset dir="${build.dir}/test">
                <include name="**/*,*.xml" />
            </fileset>
        </delete>
    </target>

</project>

顺便说一下.您不应该在 dir 参数中使用 .(点).如果你想删除你有 build.xml 文件的目录中的文件，你应该传递绝对路径(为此你可以使用 <dirname/> 像我的例子).如果您将使用 . 那么您将遇到嵌套构建的问题.让我们想象一下，你有两个删除文件的构建，但第一个构建也调用了第二个构建:

By the way. You shouldn't use . (dot) in you dir argument. If you want to delete files in directory where you have got build.xml file you should pass absolute path (to do this you can use <dirname/> like in my example). If you will use . then you will have problems with nested build. Let's imageine that you have got two builds which delete files but first build also call second build:

maindir/build1.xml

maindir/build1.xml

<delete dir="." includes="**/*.txt" />
<!-- call clean target from build2.xml -->
<ant file="./subdir/build2.xml" target="clean"/>

maindir/subdir/build2.xml

maindir/subdir/build2.xml

<delete dir="." includes="**/*.txt" />

在这种情况下，build2.xml 不会删除 subdir 中的 *.txt 文件，而是删除 maindir 中的 *.txt 文件，因为 ant 属性将传递给 build2.xml.当然，您可以使用 inheritAll="false" 来省略这一点，但根据我的经验，我知道在路径中使用 . 会给您带来很多问题.

In this case build2.xml won't delete *.txt files in subdir but *.txt files in maindir because ant properties will be passed to build2.xml. Of course you can use inheritAll="false" to omit this but from my experience I know that using . in paths will bring you a lot of problems.
