powershell - 通过 PowerShell 调用批处理文件时出现问题

Question

我在尝试通过 PowerShell 调用批处理文件时遇到一些问题。当我运行批处理文件本身时，一切正常；下面是我的 PS 代码

cmd.exe /c "C:\Source\BuildSource\SATCOM\EBEM\LCT GUI 02.01.04\run_ebem_lct_020104.bat"

下面是我的批处理文件

@title EBEM LCT 02.01.04
PathTemp=%Path%
# Path=C:\Program Files\jre7\bin;%Path%
Path=C:\Program Files\jre7\bin;%Path%
start javaw -classpath .\EBEM_LCT_020104.jar;comm.jar ebem_lct.system.LCT_Client Path=%PathTemp% PathTemp= exit

最后，下面是 PS 回复给我的内容

• 无需使用cmd/c从PowerShell调用批处理文件；只需直接调用它，在引用批处理文件路径的情况下需要使用&，call operator .

• 您的批处理文件:

  • 缺少 @echo off 以在执行命令之前抑制命令的回显
  • 错误地尝试在不使用 SET 命令的情况下设置环境变量
  • 错误地尝试使用 # 启动行注释。

总的来说，代码看起来像是从 Bash shell 脚本复制而来，并且不太适合 cmd.exe。

从 PowerShell 调用:

& "C:\Source\BuildSource\SATCOM\EBEM\LCT GUI 02.01.04\run_ebem_lct_020104.bat"

修复了批处理文件内容:

@echo off
setlocal

:: Set the window title - this will revert when the batch file exits,
:: so there is little point in doing this, given that `start` below
:: launches the application *asynchronously* and the batch file therefore
:: exits quickly.
title EBEM LCT 02.01.04

:: Temporarily add a folder to the PATH.
:: Thanks to `setlocal`, there is no need to restore the previous path afterwards.
Set "Path=C:\Program Files\jre7\bin;%Path%"

:: Start the application
start javaw -classpath .\EBEM_LCT_020104.jar;comm.jar ebem_lct.system.LCT_Client

替代方案是完全不用批处理文件，全部在 PowerShell 中完成:

# Save the previous $env:Path value and temporarily prepend a new folder.
$prevPath, $env:Path = $env:Path, "C:\Program Files\jre7\bin;$env:Path"

# Invoke the (GUI) application, which launches asynchronously.
javaw -classpath .\EBEM_LCT_020104.jar;comm.jar ebem_lct.system.LCT_Client

# Restore the original $env:Path value.
$env:Path = $prevPath
