why am I not able to run batch file in jenkins pipeline running in windows 10?

Question

I'm trying to run a batchscript present inside the workspace of jenkins. I have written a groovy script as below to do this

stage('batchscript') {
   steps{
      bat 'start cmd.exe /c C:\Program Files (x86)\Jenkins\workspace\jenkins Project\batchfile.bat'
   }
}

when I build the job it should open a new command window and run my batch file in a new command prompt executing all the bat commands. The build is succesful but no command window opens up. Any suggestion will be helpfull

Jenkins is aimed to execute shell commands in background mode, not for interactive(UI) mode. When you run start cmd.exe /c c://some/app.exe a new cmd UI is opened and this will never happen in jenkins.

Single line

If you need to execute a simple batch commands with jenkins :

stage('build') {
      cmd_exec('echo "Buils starting..."')
      cmd_exec('echo "dir /a /b"')
}

def cmd_exec(command) {
    return bat(returnStdout: true, script: "${command}").trim()
}

Here a advanced example :

Multiline

steps {
  echo 'Deploy to staging environment'

  // Launch tomcat
  bat """
    cd c:\qa\bin
    dir /a /b
    startup
  """
  
  bat """
    cd c:\qa\bin
    startup
  """

  // Code to move WAR to Tomcat
  bat "xcopy /y c:\webapp\target\webapp.war ..."
  bat "xcopy /y c:\webapp\target\webapp.war ..."
}

Invoke batch file

If you need to execute a batch file with jenkins :

stage('build') {
  dir("build_folder"){
      bat "run_build_windows.bat"
  }
}

or

stage('build') {
  bat "c://some/folder/run_build_windows.bat"
}

Windows paths some time are bizarre :s . Anyway, linux is the best choice to host jenkins.
