当试图制作一个Jenkins项目时，我观察到一个奇怪的行为，该项目的Ant步骤接受Ant使用的任何String参数。它看起来像Ant以某种方式收到一些格式不正确的内容作为参数。从Jenkins Ant Plugin将参数传递给Ant
首先我登录安装在詹金斯在同一系统上，并写了一个简单的Ant构建文件：
<?xml version="1.0"?>
<!--DOCTYPE project PUBLIC "-//ANT//DTD project//EN" "/usr/src/ant/project.dtd"-->
<project name="many-params" default="run">
<target name="run">
<echo message="first Param: ${firstparam}"/>
<echo message="second Param: ${secondparam}"/>
</target>
</project>
然后我跑了设置参数的蚂蚁，得到了预期的输出：
$ ant -Dfirstparam=A -Dsecondparam=B
Buildfile: /tmp/build-dir/build.xml
run:
[echo] first Param: A
[echo] second Param: B
BUILD SUCCESSFUL
Total time: 0 seconds
接下来，我开始在Jenkins设定一个项目。我詹金斯系统规格如下：
- OS： Linux的AMD64 2.6.32-504.1.3.el6.x86_64
- 詹金斯：版本。 1.618
- JRE詹金斯在其上运行：甲骨文1.7.0_55-b13中
- 蚂蚁插件版本： 1.2
- JRE用于项目：甲骨文45年1月6日32位
- 蚂蚁用于该项目： 1.8.2
我已经设置了8个连续步骤的作业，4个准备shell脚本块，重写b具有略微不同的参数名称（没有分隔符，破折号分隔符，点分隔符）的uild.xml以及4个调用ant的Ant构建步骤，尝试传递相应的参数。
从作业目录的准备config.xml文件看起来像：
<?xml version='1.0' encoding='UTF-8'?>

建设任务给了我下面的输出：

所以出现这种情况很多问题：
- 为什么STEP 1中根本没有打印任何值？
- 如何在第2步中使用字符串值“第一”和“第二”而不是“A”和“B”？
- 为什么在第3步格式不正确的行“-Dparam-first = A param-second = B”（通过将两个参数放在Jenkins步骤设置中的同一行上产生：param-first = a param-second = B）以及步骤2中的“-Dparam-first = A -Dparam-second = B”？我应该在这里失败，就像我在shell中运行一样。
- 步骤4中的点有什么问题？为什么它会在这里产生一个错误的替代错误？
非常感谢您对这些问题的任何建议。
谢谢！即使重写了build.xml，转义美元符号也彻底解决了我的问题。我觉得自己像个白痴一样没有想出来！ –
不要那么想。直到我运行你的配置并查看了生成的'build.xml'文件，我才发现它自己 – Slav
