Jenkins - cmd is not recognized

Question

Environment:

• Master Linux Jenkins server
• Two Windows slave nodes
• The windows slaves are running as a service

First Test

• I create a Pipeline and use a use a "Execute Windows batch command" in the build section
• In the Command box I put "C:\Jenkins\mytest.bat"
• I checked the box "Restrict where this project can be run" and write down the name of the Windows slave
• I built the pipeline and was successful

Second Test

• I create a Declarative Pipeline as follows:

  pipeline {  
      agent { label 'SiebelWindows' }
  
      stages {
          stage('Test Bat') {
             steps { 
                          bat 'C:\\Jenkins\\mytest.bat'
                          //bat 'start cmd.exe /c C:\\Jenkins\\mytest.bat'
                          //call C:\\Jenkins\\mytest.bat
                          }
                  }
      }
     }
  

• In this case the build FAIL with error "cmd is not recognized as a internal o external command"

So, why can I run the .bat with a non-declarative pipeline, but fails with a declarative pipeline?

Answer 1

When I display the "Path" and the "PATH" variables, this was the result

Original_Path

The solution was redefine the PATH enviorement variable, like this

environment {

    PATH = "C:\\WINDOWS\\SYSTEM32"

}

@JustAProgrammer aske me if C:\WINDOWS\SYSTEM32 was in the PATH of my Windows machine, and that is correct, but seems like Jenkins master do not know the slave's Windows Path.

I resolve my issue, but I still looking for a complete solution, I need to set the PATH enviorement variable with ALL the path, no only C:\WINDOWS\SYSTEM32
