Ant exec - 无法运行程序“start”创建进程错误=2

发布于 2024-08-15 18:21:02 字数 691 浏览 2 评论 0 原文

我无法使用 ant exec 运行 Windows“启动”。蚂蚁版本1.7.1。

这是示例 build.xml，用于重现

<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的问题：

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 promt 手动运行“start cmd /c notepad”。

关于如何解决这个问题有什么建议吗？

干杯作为

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

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>

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

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.

Any suggestions on how to fix this?

cheers

start 不是可执行文件，而是 cmd.exe shell 的内部命令，因此要启动您必须执行的操作：

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

编辑：

对于生成多个窗口，这应该有效：

<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>

但您提到spawn =“true”不适用对于您的环境，这是为什么？

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>

EDIT:

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>

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

我的解决方案

<project name="test"  basedir="." default="test-target">
<target name="start-init">
        <exec executable="where" outputproperty="START">
            <arg line="start" />
        </exec>
</target>
<target name="test-target">
        <exec executable="${START}">
            <arg line="cmd /c notepad" />  
        </exec>      
</target>
</project>

my solution

<project name="test"  basedir="." default="test-target">
<target name="start-init">
        <exec executable="where" outputproperty="START">
            <arg line="start" />
        </exec>
</target>
<target name="test-target">
        <exec executable="${START}">
            <arg line="cmd /c notepad" />  
        </exec>      
</target>
</project>
