无法在phing XML中使用EOF分隔的此处文档 [英] Unable to use here-document delimited by EOF within phing XML

问题描述

切换到其他用户后，我有一些命令要运行.我需要在构建xml文件中执行此操作.

I have some commands to be run after switching to a different user. I need to do this in a build xml file.

以下是我所做的-

<exec command="sudo su auto_deploy &lt;&lt; EOF
echo 'Logged in user'
whoami
EOF" dir="${dir.scratchpad}" />

我使用了XML转义，即& lt; 表示< .

I have used XML escaping, i.e. < for <.

但是，我收到以下错误-

However, I am getting the following error -

sh: warning: here-document at line 0 delimited by end-of-file (wanted `EOF')

相关问题-此处文档给出了意外的文件结尾"错误

更新

注意-在开始EOF之后和结束EOF之前，我没有放置任何空格.

Note - I have not put any space after the starting EOF and before the ending EOF.

更新1

添加了赏金.期望得到一个详尽的答案，因为到目前为止，我从这些评论中无法理解.请原谅我缺乏知识.

Added bounty. Expecting an elaborate answer because I am unable to make much sense from the comments so far. Pardon my lack of knowledge.

更新2

以防万一，我正在研究Phing，上面提到的XML来自Phing允许用户编写的build xml文件，以完成与部署相关的工作.

Just in case it was not clear, I am working on Phing, and the XML that I mentioned above is from the build xml file that Phing allows a user to write, to do deployment related stuff.

更新3

正如@tripleee引用的问题中提到的那样，我尝试过--

As mentioned in the question referenced by @tripleee, I tried with this -

  <exec command="sudo su auto_deploy &lt;&lt; EOF${line.separator}echo 'Logged in user'${line.separator}whoami${line.separator}EOF" dir="${dir.scratchpad}" />

，但仍会引发相同的错误.不知道我在想什么.

but it still throws the same error. Not sure what am I missing.

推荐答案

我以前从未使用过phing，但是从文档中看，似乎有两种方法可以解决您的问题.首先，使用 -verbose 选项，如果您在最终的 EOF 之后添加其他换行符，则原始解决方案似乎可以正常工作.也就是说，如果我有这个 build.xml :

I've never used phing before, but looking at the documentation it looks like there are a couple of ways to solve your problem. First, using the -verbose option it looks like your original solution might Just Work if you add an additional newline after the final EOF. That is, if I have this build.xml:

<?xml version="1.0"?>
<project name="chamilo" default="clean" basedir=".">
<target name="test">
<exec command="sudo -u deploy bash &lt;&lt;EOF${line.separator}echo Logged in user;whoami${line.separator}EOF" />
</target>
</project>

然后我运行 phing-详细测试，我看到了:

And I run phing -verbose test, I see:

     [exec] Executing command: sudo -u deploy bash <<EOF
echo Logged in user;whoami
EOF 2>&1
sh: line 2: warning: here-document at line 0 delimited by end-of-file (wanted `EOF')
     [exec] Logged in user
     [exec] deploy
     [exec] bash: line 2: EOF: command not found

查看所生成脚本的最后一行，如下所示:

Look at the final line of the generated script, which looks like:

EOF 2>&1

如果我添加其他换行符，例如:

If I add an additional newline, like this:

<?xml version="1.0"?>
<project name="chamilo" default="clean" basedir=".">
<target name="test">
<exec command="sudo -u deploy bash &lt;&lt;EOF${line.separator}echo Logged in user;whoami${line.separator}EOF${line.separator}" />
</target>
</project>

然后它就可以工作了:

     [exec] Executing command: sudo -u deploy bash <<EOF
echo Logged in user;whoami
EOF
 2>&1
     [exec] Logged in user
     [exec] deploy
