我要编写非常复杂的ant任务。我不得不制作单独的构建文件，剩下1个。 共有4个文件：
buildpackage.bat, buildpackage.xml, buildpackage.txt, structure.xml
buildpackage.bat只是一个调用buildpackage.xml "ant -f buildpackage.xml"的ant文件。那样就好。
buildpackage.txt很简单，并且有逗号分隔的行：
server1,client1
server2,client2
genericserver,client[x]
server[x],client[x]
始终有服务器名称和客户端名称：
Server name可以是字母，数字和字母，但长度可变。
Client name - 仅限字母。
我需要将这些文件拆分为两个独立的变量：server.name和client.name。
我所做的是：
<loadfile property="buildpackage" srcFile="buildpackage.txt"/>
<for list="${buildpackage}" param="depl.det" delimiter="${line.separator}">
<sequential>
<echo>
Input: @{deploy.details}
</echo>
</sequential>
</for>
我得到的结果是：
[echo] Input: server_01,Client_01
[echo] Input: server_02,Client_02
[echo] Input: server_03,Client_03
[echo] Input: clientserver,client_04
我希望server_01为parameter1，client_02为parameter2。
我将按顺序执行其他任务。我将文件从客户端[x]目录复制到服务器[x]（这很简单，但如何将该字符串拆分为2个单独的变量？）。
现在是非常复杂的任务。
我也有structure.xml文件。结构是：
<core>
<clients>
<client>
<name>Client_01</name>
<branding>brand_01</branding>
<applications>
<application>application_01</application>
</applications>
<solutions>
<solution>solution01</solution>
</solutions>
</client>
<client>
<name>Client_07</name>
<branding>brand_09</branding>
<applications>
<application>application_03</application>
</applications>
<solutions>
<solution>solution01</solution>
<solution>solution07</solution>
<solution>solution08</solution>
</solutions>
</client>
<clients>
<core>
我有很多客户，应用程序，品牌，解决方案。每个客户只能有1个应用程序和1个品牌，但有多个解决方案。
根据以前的顺序任务（获取服务器和名称），我必须遍历该xml文件并获取每个匹配的客户端（来自上一个任务）
- branding
- application
- solutions (multiple or one)
我可以使用<xmlproperty>读取XML，但我不知道如何顺序执行（迭代）并获取匹配的属性。
我知道这很复杂。摘要是：
${client.name}作为参数并循环遍历structure.xml。它找到匹配的品牌/应用程序/解决方案，并为每个匹配的客户输出它。输出：
server.name
client.name
branding.name
application name
solution [X]
solution [y]
必须为每个服务器/客户端处理Ant。如果我有属性，我可以完成构建的其余部分并进行编译。我无法触摸structure.xml。我可以做我需要/想要buildpackage.cml和buildpackge.txt的所有内容。 Buildpackage.txt可以替换为.xml文件或任何文件（例如.properties）。它必须包含那两个值服务器和客户端。
感谢您的帮助。
现在我遇到了问题。
如果我将相同的应用程序2x放入构建文件中，则只构建第一个。
这是我的build.xml文件

如果我尝试构建buildpackage.txt文件
client1=server1
client2=server1
client1=server2
我知道了 client1-＆gt; server1，client2-＆gt; server1但......没有客户端1到server2
全部修复。 scp任务的解决方案是：
<!-- scp file to remote server -->
<property name="scp_username" value="XXX"/>
<property name="scp_password" value="YYY"/>
<property name="scp_remote_directory" value="path"/>
<for list="${@{client}}" delimiter="=" param = "val">

<property name="token" value="@"/>
<scp trust="true" verbose="true" localFile="${dest.dir}/@{client}/@{client}.zip" remoteTodir="${scp_username}:${scp_password}${token}@@{val}:${scp_remote_directory}"/>
</sequential>
</for>
一切正常。 谢谢你的帮助
答案 0 :(得分：1)
对于任何xmldriven构建，我建议使用ant addon xmltask，所以类似于：
（假设buildpackage.txt和structure.xml中的客户端名称相似 - 您的代码段有多个名称Client_01，client1 ..！？）
<project>
<!-- Import XMLTask -->
<taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask"/>
<!-- make buildpackage.txt a valid propertyfile to get the job done
f.e. server1,client1 will get client1=server1 etc. ..
to make server easily accessible within xml loop
-->
<replaceregexp
file="buildpackage.txt"
match="(.+),(.+)"
replace="\2=\1"
byline="true" />
<!-- now load that file -->
<property file="buildpackage.txt"/>
<!-- loop over all clients -->
<xmltask source="structure.xml">
<call path="//client">
<param path="name/text()" name="client"/>
<param path="branding/text()" name="branding"/>
<param path="applications/application/text()" name="application"/>
<!-- inside action adress params with @{..} syntax ! -->
<actions>
<!-- the copy (or whatever) action
here demonstrated with echoxml -->
<echoxml>
<!-- access the corresponding server (set via buildpackage.txt)
with nested ${@{..}} syntax ! -->
<copy todir="//${@{client}}/share">
<fileset dir="@{client}/somedir"/>
</copy>
</echoxml>
<echo>${@{client}}${line.separator}@{client}${line.separator}@{application}${line.separator}@{branding}</echo>
<!-- another nested xmltask for loop over solutions -->
<xmltask source="structure.xml">
<call path="//client[name/text()='@{client}']/*/solution">
<param path="text()" name="solution"/>
<actions>
<echo>@{solution}${line.separator}</echo>
</actions>
</call>
</xmltask>
</actions>
</call>
</xmltask>
</project>
如果可能，您应该将buildpackage.txt创建为有效的属性文件
格式=＆gt;客户端[x] =服务器[x]立即。
然后你需要的只是xmltask。将所有步骤完成到嵌套操作部分，如echoxml / copy所示。
输出：
<?xml version="1.0" encoding="UTF-8"?>
<copy todir="//server1/share">
<fileset dir="client1/somedir" />
</copy>
[echo] server1
[echo] client1
[echo] application_03
[echo] brand_01
[echo] solution01
<?xml version="1.0" encoding="UTF-8"?>
<copy todir="//server4/share">
<fileset dir="client4/somedir" />
</copy>
[echo] server4
[echo] client4
[echo] application_03
[echo] brand_09
[echo] solution01
[echo] solution07
[echo] solution08
BUILD SUCCESSFUL
- 关于条件操作的问题后编辑，仅在设置了$ {@ {client}}时
如果propertyfile buildpackage.txt包含错误的属性，则表示server = client而不是client = server，f.e。 ：
Sol-e-45-D=PRODUCTION1
CONNECTION=PRODUCTION3
PRODUCTION4=DFHH
PRODUCTION5=MEGA-5
你需要一些if isset逻辑。最好是使用new if/unless feature（与ant191一起介绍），如果你对ant＆gt; = 1.9.3，f.e。 ：
<!-- you need to activate that feature via namespaces -->
<project
xmlns:if="ant:if"
xmlns:unless="ant:unless"
>
<!-- Import XMLTask -->
<taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask"/>
<!-- load propertyfile with client=server mappings -->
<property file="buildpackage.txt"/>
<!-- loop over all clients -->
<xmltask source="structure.xml">
<call path="//client">
<param path="name/text()" name="client"/>
<param path="branding/text()" name="branding"/>
<param path="applications/application/text()" name="application"/>
<!-- inside action adress params with @{..} syntax ! -->
<actions>
<!-- the copy (or whatever) action
here demonstrated with echoxml -->
<echoxml if:set="@{client}">
<!-- access the corresponding server (set via buildpackage.txt)
with nested ${@{..}} syntax ! -->
<copy todir="//${@{client}}/share">
<fileset dir="@{client}/somedir"/>
</copy>
</echoxml>
<echo if:set="@{client}">${@{client}}${line.separator}@{client}${line.separator}@{application}${line.separator}@{branding}</echo>
<!-- another nested xmltask for loop over solutions -->
<xmltask source="structure.xml">
<call path="//client[name/text()='@{client}']/*/solution">
<param path="text()" name="solution"/>
<actions>
<echo if:set="@{client}">@{solution}${line.separator}</echo>
</actions>
</call>
</xmltask>
</actions>
</call>
</xmltask>
</project>
注意=＆gt; xmltask调用也有一个if属性，但是在启动循环时不知道客户端名称，不能使用<call path="//client" if="@{client}">
输出：
<?xml version="1.0" encoding="UTF-8"?>
<copy todir="//PRODUCTION1/share">
<fileset dir="Sol-e-45-D/somedir" />
</copy>
[echo] PRODUCTION1
[echo] Sol-e-45-D
[echo] Sol-e-45-D
[echo] Branding-BLUE
[echo] Sol-e-45-D
<?xml version="1.0" encoding="UTF-8"?>
<copy todir="//PRODUCTION3/share">
<fileset dir="CONNECTION/somedir" />
</copy>
[echo] PRODUCTION3
[echo] CONNECTION
[echo] Sol-e-45-D
[echo] Branding-BLUE
[echo] Sol-e-45-D
否则当绑定到ant＆lt; = 1.9.3时，你可以使用antcontrib作为任务，因为你已经在你的代码片段中有了taskdef：
<if>
<isset property="@{client}"/>
<then>
<!-- ... -->
</then>
</if>
当心，你的antcontrib taskdef定义错误 !!，antcontrib.properties只包含ant＆lt;的taskdef。 1.6，声明它（假设antcontrib.jar已经在路径上）：
<project xmlns:ac="antlib:net.sf.antcontrib">
<ac:if>
...
或没有名称空间：
<project>
<!-- Import AntContrib -->
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
...
