Command line length limitation of 127 characters

I’m doing embedded development and IAR is used.

In jenkinsfile, IAR is called by the following command:

bat “"$IAR_BUILD_EXE" "${projectFilePathStr}" -build "${config.key}" -log warnings”

and it will be expended as following:

“C:\Program Files\IAR Systems\Embedded Workbench 9.2\common\bin\IarBuild.exe” “FireSG_DWC\make\LPC5000\IAR9\App.ewp” -build “FireSG_DWC_HardMELSI_AppBoot_Release” -log warnings

Today I find a command line length limitation while doing IAR post-build.
From jenkins console output,

FAILED: C:/JenkinsBuilder/workspace/Test/FireSG_DWC/make/LPC5000/IAR9/FireSG_DWC_HardMELSI_AppBoot_Release/Post-Link Action 1
cmd /C cd C:\JenkinsBuilder\workspace\Test\FireSG_DWC\make\LPC5000\IAR9 && powershell -command Copy-Item "C:\JenkinsBuilder\workspace\Test\FireSG_DWC\make\LPC5000\IAR9\FireSG_DWC_HardMELSI_AppBoot_Release\Exe\FireSG_DWC_HardMELSI_AppBoot_Release.hex" “C:\JenkinsBuilder\workspace\Test\FireSG_DWC\make\LPC5000\IAR9......\bin\LPC5000\FireSG_DWC_HardMELSI_AppBoot_Release.hex”
Copy-Item : Can not find the path “C:\JenkinsBuilder\workspace\Test\FireSG_DWC\make\LPC5000\IAR9\FireSG_DWC_HardMELSI_AppBoot_Relea
se\Exe\FireSG_DWC_HardMELSI_AppBoot_Release.hex”,Path not exist

The command was truncated and the first 127 characters are: "powershell -command Copy-Item “C:\JenkinsBuilder\workspace\Test\FireSG_DWC\make\LPC5000\IAR9\FireSG_DWC_HardMELSI_AppBoot_Relea”

I’ve tried run this commands in jenkins agent manually:

cmd /C cd C:\JenkinsBuilder\workspace\Test\FireSG_DWC\make\LPC5000\IAR9 && powershell -command Copy-Item “C:\JenkinsBuilder\workspace\Test\FireSG_DWC\make\LPC5000\IAR9\FireSG_DWC_HardMELSI_AppBoot_Release\Exe\FireSG_DWC_HardMELSI_AppBoot_Release.hex” “C:\JenkinsBuilder\workspace\Test\FireSG_DWC\make\LPC5000\IAR9......\bin\LPC5000\FireSG_DWC_HardMELSI_AppBoot_Release.hex”

It runs correctly. So I don’t think it’s the limitation of cmd it self.

I’m not sure why it has a length limitation when executed by jenkins.

Any help is appreciated.
