输入传递到Ant的＆LT;＆EXEC GT;任务 [英] Passing input to Ant's <exec> task

问题描述

我必须采取在inputed密码后，运行标准-task Ant脚本：

 ＆LT;输入消息=密码：方法addProperty =密码＆GT;
＆LT;处理器类名=org.apache.tools.ant.input.SecureInputHandler/＆GT;
＆LT; /输入＆GT;＆LT; EXEC可执行=/ bin / sh的输入=$ {}密码failonerror =真＆GT;
    ＆LT; ARG行=' -  CmyScript.sh/＆GT;
＆LT; / EXEC＆GT;
 

脚本myScript.sh会提示用户输入密码，而且，这是我的理解是从输入的应该是继电器输入无论＆LT在Ant文件; EXEC＆GT; 任务执行，而是我得到（用于输入密码foobar的）

  [执行]无法打开的/ usr /本地/ foobar的
 

随后是从我的脚本抱怨的密码不正确的堆栈跟踪...所以显然我已经理解的文档错误。是否有人知道如何处理来自外部脚本提示输入蚂蚁？

解决方案

 输入=$ {}密码
 

这将尝试从文件$ {}密码读取和内容发送到脚本。尝试使用：

  inputstring =$ {}密码
 

来代替。这将发送字符串本身而不是把它像一个文件名

I have an Ant script running a standard -task after taking in an inputed password:

<input message="Password:" addproperty="password">
<handler classname="org.apache.tools.ant.input.SecureInputHandler" />
</input>

<exec executable="/bin/sh" input="${password}" failonerror="true">
    <arg line='-c "myScript.sh"' />
</exec>

The script myScript.sh prompts the user for a password, and, it was my understanding that from the Ant documentation that input is supposed relay input into whatever the <exec> task is executing, but instead I get (for entering the password foobar)

[exec] Failed to open /usr/local/foobar

which is followed by a stack trace from my script complaining about an incorrect password...so obviously I've understood the documentation wrong. Does anybody know how to handle prompted input from external scripts in Ant?

解决方案

input="${password}"

This will try to read from the file ${password} and send the contents into your script. Try using:

inputstring="${password}"

instead. This will send the string itself instead of treating it like a filename
