如何在蚂蚁中逃避反斜杠 [英] how to escape backslash in ant

问题描述

我正在编写 Ant 脚本.

I am writing Ant scripts.

我有一个属性值:"C\:Program Files\\test1\\test2"

I have a property which has the value: "C\:Program Files\\test1\\test2"

Ant 中有没有一种方法可以将其转换为:C:Program Files\test1\test2

Is there a method in Ant to convert it to: C:Program Files\test1\test2

推荐答案

您可以使用:http://ant-contrib.sourceforge.net/tasks/tasks/propertyregex.html

虽然我不确定这是否会满足您的要求.当您回显您的属性时，反斜杠是否可见?

although I am not sure if this will do what you are asking for. Are the backslashes visible when you echo your property?

无论如何要使用上述任务，您都必须安装 ant-contrib 并简单地编写如下任务:

In any case to use the above task you will have to have ant-contrib installed and simply write a task like this :

<project name="test" default="build">
<!--Needed for antcontrib-->
<taskdef resource="net/sf/antcontrib/antlib.xml"/>

<target name="build">

    <property name="path" value="C\:Program Files\\test1\\test2"/>
    <echo message="Path with slashes : ${path}"/>
    <propertyregex  property="removed.backslash.property"
                input="${path}"
                global="true"
                regexp="\\(\\|:)"
                replace="\1"
    />
    <echo message="Path with single slashes : ${removed.backslash.property}"/>
</target>

</project>

输出:

build:
 [echo] Path with slashes : C\:Program Files\\test1\\test2
 [echo] Path with single slashes : C:Program Files\test1\test2

此外，您可以使用任何 BSF 语言:

In addition you could use any of the BSF languages :

前提是您使用的是 jre 1.6 及更高版本.

provided you are using jre 1.6 and above.
