bash - Jenkins pipeline sh fail with "cannot run program nohup" on windows

Question

I have windows 10 and I want to execute the sh command in the Jenkinsfile from Jenkins pipeline using bash for Ubuntu for windows, but it doesn't work

I have the following stage in my Jenkins pipeline :

stage('sh how to') {
        steps {
            sh 'ls -l'
        }
    }

The error message is :

[C:Program Files (x86)Jenkinsworkspacepipelineascode] Running shell script Cannot run program "nohup" (in directory "C:Program Files (x86)Jenkinsworkspacepipelineascode"): CreateProcess error=2, Le fichier spécifié est introuvable

I tried changing Jenkins parameter->shell executable with

C:WindowsSystem32ash.exe

but same error...

how to run sh script using windows 10's bash?

From a very quick search, it looks like your error is related to the following issue : JENKINS-33708

The main cause looks like the sh step is not supported on the Windows. You may use bat or install Cygwin for instance.

Nevertheless two solutions were proposed in the previous link, suggesting you to do the following steps :

• Install git-bash
• Ensure the Gitin folder (i.e.: C:Program FilesGitin) is in the global search path, in order for Jenkins to find sh.exe
• Make nohup available for Jenkins, doing the following in git-bash (adapt your paths accordingly) :
  • mklink "C:Program FilesGitbin ohup.exe" "C:Program Filesgitusrin ohup.exe"
  • mklink "C:Program FilesGitbinmsys-2.0.dll" "C:Program Filesgitusrinmsys-2.0.dll"
  • mklink "C:Program FilesGitbinmsys-iconv-2.dll" "C:Program Filesgitusrinmsys-iconv-2.dll"
  • mklink "C:Program FilesGitbinmsys-intl-8.dll" "C:Program Filesgitusrinmsys-intl-8.dll"

Depending on your installation you may have to use these paths :

• mklink "C:Program FilesGitcmd ohup.exe" "C:Program Filesgitusrin ohup.exe"
• mklink "C:Program FilesGitcmdmsys-2.0.dll" "C:Program Filesgitusrinmsys-2.0.dll"
• mklink "C:Program FilesGitcmdmsys-iconv-2.dll" "C:Program Filesgitusrinmsys-iconv-2.dll"
• mklink "C:Program FilesGitcmdmsys-intl-8.dll" "C:Program Filesgitusrinmsys-intl-8.dll"
