Ant exec - 无法运行程序 'start' CreateProcess 错误=2 [英] Ant exec - cannot run program 'start' CreateProcess error=2

问题描述

我无法使用 ant exec 运行 windows 'start'.蚂蚁版本1.7.1.

I can't run the windows 'start' using ant exec. Ant version 1.7.1.

这是重新创建问题的示例 build.xml

Here is sample build.xml to recreate the problem

<project name="test"  basedir="." default="test-target">
<target name="test-target">
        <exec executable="start">
            <arg line="cmd /c notepad" />  
        </exec>      
</target>
</project>

执行此构建文件时出现以下错误:

getting the following error when I execute this build file:

Execute failed: java.io.IOException: Cannot run program "start": Cre
ateProcess error=2, The system cannot find the file specified

我的环境是 Windows XP，Ant 1.7.1我正在尝试从 DOS 提示符运行它.我排除了任何与 PATH 相关的问题，因为我可以从 DOS 提示符手动运行start cmd/c notepad".

My env is Windows XP, Ant 1.7.1 I am trying to run this from DOS prompt. I rule out any PATH related issues, as I could run 'start cmd /c notepad' from DOS promt manually.

有关如何解决此问题的任何建议?

Any suggestions on how to fix this?

干杯一个

推荐答案

start 不是可执行文件，而是 cmd.exe shell 的内部命令，因此要启动某些内容，您必须:

start is not an executable but is an internal command of the cmd.exe shell, so to start something you'd have to:

<exec executable="cmd.exe">
        <arg line="/c start notepad" />  
    </exec>

对于生成多个窗口，这应该有效:

For spawning multiple windows, this should work:

<target name="spawnwindows">
    <exec executable="cmd.exe" spawn="yes">
        <arg line="/c start cmd.exe /k echo test1" />  
    </exec>
    <exec executable="cmd.exe" spawn="yes">
        <arg line="/c start cmd.exe /k echo test2" />  
    </exec>
</target>

但是您提到 spawn="true" 不适用于您的环境，这是为什么呢?

but you mentioned that spawn="true" is not applicable for your environment, why is that?
