Run a command shell in jenkins

问题:

I'm trying to execute a command shell in Jenkins, I'm working on Windows 7. In the console output I have this:

Building in workspace C:\Program Files (x86)\Jenkins\workspace\test
[test] $ sh -xe C:\Windows\TEMP\hudson6299483223982766034.sh
The system cannot find the file specified

Any idea?

回答1:

For Windows slave, please use Execute Windows batch command.
For Unix-like slave like linux or Mac, Execute shell is the option.

As far as I know, Windows will not support shell scripts out of the box. You can install Cygwin or Git for Windows, go to Manage Jenkins > Configure System Shell and point it to the location of sh.exe file found in their installation. For example:

C:\Program Files\Git\bin\sh.exe

There is another option I've discovered. This one is better because it allowed me to use shell in pipeline scripts with simple sh "something".

Add the folder to system PATH. Right click on Computer, click properties > advanced system settings > environmental variables, add C:\Program Files\Git\bin\ to your system Path property.

IMPORTANT note: for some reason I had to add it to the system wide Path, adding to user Path didn't work, even though Jenkins was running on this user.

An important note (thanks bugfixr!):

This works. It should be noted that you will need to restart Jenkins in order for it to pick up the new PATH variable. I just went to my services and restated it from there.

Disclaimer: the names may differ slightly as I'm not using English Windows.

Error shows that script does not exists

The file does not exists. check your full path

C:\Windows\TEMP\hudson6299483223982766034.sh
The system cannot find the file specified

Moreover, to launch .sh scripts into windows, you need to have CYGWIN installed and well configured into your path

Confirm that script exists.

Into jenkins script, do the following to confirm that you do have the file

cd C:\Windows\TEMP\
ls -rtl
sh -xe hudson6299483223982766034.sh

This is 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
