我尝试将ini文件解析为我可以在我的ant脚本中使用的属性。我有以下内容：
<project name="DeployScript" default="deploy-staging" basedir=".">
<taskdef resource="net/sf/antcontrib/antcontrib.properties" />
<!-- The location of the settings.ini file -->
<property name="ini-file" location="../settings.ini" />
<loadfile property="iniConfig" srcFile="${ini-file}"/>
<target name="deploy-staging"
description="Deploy project to staging environment" >
<echo message="Ini file: ${ini-file}" />
<echo message="${lib}" />
<echo message="${store_dir}" />
<echo message="${ant.home}" />
<!--- walk the ini file's lines -->
<foreach list="${iniConfig}"
target="echoMsg"
param="line"
delimiter="${line.separator}" />
<echo message="HERE: ${prevSection}" />
</target>
<property name="prevSection" value="" />
<!-- this is executed for every line in the ini file. -->
<target name="echoMsg">
<!-- strip out the section name, variable name and value (if exists on the line) -->
<propertyregex property="secm"
input="${line}"
regexp="^\[(.*)\]"
select="\1"
casesensitive="false" />
<propertyregex property="name"
input="${line}"
regexp="^([\S]+)\s*=\s*([^;]+)"
select="\1"
casesensitive="false"
defaultValue="" />
<propertyregex property="value"
input="${line}"
regexp="^([\S]+)\s*=\s*([^;]+)"
select="\2"
casesensitive="false"
defaultValue="" />
<!-- overwrite the previous section if we have found a new one. -->
<if>
<isset property="secm" />
<then>
<echo message="PREVSECTION IS SET" />
<property name="prevSection" value="${secm}" />
</then>
</if>
<!-- display the information about the found data -->
<echo message="line = ${line}" />
<echo message="section = ${secm}" />
<echo message="name = ${name}" />
<echo message="value = ${value}" />
<echo message="new last section: ${prevSection}" />
<echo message="----" />
</target>
</project>
我尝试做的是解析所有名称=值对并将它们放在以下属性中：section.name = value;
不知何故，该部分未在“echoMsg”目标中被记住。我希望记住部分名称。
所以，
[global]
name=var
name2=val
[section2]
name=var
应该成为：
global.name=var
global.name2=val
section2.name=var
这是我的蚂蚁脚本的输出：
echoMsg:
[echo] PREVSECTION IS SET
[echo] line = [global]
[echo] section = global
[echo] name =
[echo] value =
[echo] new last section: global
[echo] ----
echoMsg:
[echo] line = servername = my-server.local ; Server name
[echo] section = ${secm}
[echo] name = servername
[echo] value = mac-mini-van-Peter.local7
[echo] new last section: ${prevSection}
[echo] ----
如您所见，最后一个“$ {prevSection}”未设置。我希望它是“全球性的”。
我尝试使用而不是属性，但没有区别。

这是一个提示：尝试在<propertyregex>语句之前添加一个echo部分，以查看各种属性的值。
我添加了这些<echo>行......
<target name="echoMsg">
<!-- strip out the section name, variable name and value (if exists on the line) -->
<echo message="prev line = ${line}" />
<echo message="prev section = ${secm}" />
<echo message="prev name = ${name}" />
<echo message="prev value = ${value}" />
<echo message="prev new last section: ${prevSection}" />
<echo message="----" />
现在让我们看一下输出：
deploy-staging:
[echo] Ini file: /Users/david/property.ini
[echo] ${lib}
[echo] ${store_dir}

[echo] prev name = ${name}
[echo] prev value = ${value}
[echo] prev new last section:

[echo] line = [global]
[echo] section = global
[echo] name =

对<echomsg>的每次调用都会丢失先前在<echomsg>中设置的值。
我建议您尝试<for>任务。 <for>任务不会在循环的每次迭代中丢失属性的值。但是，您必须将override设置添加到<propertyregex>任务，并使用<var>任务而不是<property>任务来重置您的属性值通过循环的每次迭代。
您还必须将<taskdef>更改为此：
<taskdef resource="net/sf/antcontrib/antlib.xml" />

这是适合我的代码。只是想与WWW分享：
<project name="DeployScript" default="deploy-staging" basedir=".">

<property name="ini-file" location="../settings.ini" />
<!-- load the ini file -->
<loadfile property="iniConfig" srcFile="${ini-file}"/>
<!-- when no section is given, the vars are stored in the "default" section -->
<var name="theSection" value="default" />
<!-- set global properties for this build -->
<target name="deploy-staging" description="" >
<echo message="Start parsing ini file" level="info" />
