I am trying to do continuous integration with Hudson and MSTest.

When I try to run this job I get the following error:

My Configuration looks like this:

My Command Line looks like this:

Answer 1

This happens if you have specified your Windows command as "Execute shell" rather than "Execute Windows batch command".

Answer 2

This happens because Jenkins is not aware about the shell path.
In Manage Jenkins -> Configure System -> Shell, set the shell path as

C:\Windows\system32\cmd.exe

Answer 3

In my case the builds worked using the "Execute shell" before doing a system reboot and migration and gave the Cannot run program "sh" after. The issue was that the system path got shorter unexpectedly. It's not clear why, but the path lost C:\Program Files (x86)\Git\bin and the version of Git I was using comes with sh.exe.

Of course, you could just change all your "Execute shell" build steps to "Execute Windows batch command" in all your jobs as suggested by @funkybro. This doesn't solve your problem if you have a job that could run on either a Windows system or Linux and you have both systems for other reasons.

Or, you could change this setting to use cmd.exe as suggested by @ajith: Manage Jenkins -> Configure System -> Shell -> Shell executable = C:\Windows\system32\cmd.exe

But, I like having linux commands and using something that more closely resembles Bash. It's my own preference but I thought this might also be helpful. To start from the beginning, I used Chocolatey NuGet to install Git. I also recommend GnuWin to give you some of the very helpful Unix commands.

• Install Chocolatey NuGet
• In CMD or PowerShell: cinst gnuwin git

Then you can fix this using the Windows UI by adding C:\Program Files (x86)\Git\bin\ to the system path.

Or you can fix it in Jenkins global config: Manage Jenkins -> Configure System -> Shell -> Shell executable = C:\Program Files (x86)\Git\bin\sh.exe
