dos "exit" command not functioning correctly

XMLWordPrintable

      if you attempt to run a dos batch file that has an "exit" command within it then the task does not notice that the interpreter has terminated.

      e.g. in workflow create a CPS with the following

      node {
      bat '''echo hello
exit 1'''
      echo 'should not be seen'
}

      This results in a workflow that will run forever.

          Isn't that what the /b flag is for?

          well that depends on your perspective.

          There is no other cmd.exe interpreter in the view of the user - so they would logically assume that the script is run with cmd.exe /k the_contents_of_the_stuff.

          regardless of that, the end result is not good - having a task running that has died looks bad for Jenkins and gives the impression of a Jenkins issue even if it is PEBKAC.

          Since I have no idea what /b or /k do I am passing back to you!

          cmd.exe /?
    Starts a new instance of the Windows command interpreter
    /K      Carries out the command specified by string but remains

          > help exit
Quits the CMD.EXE program (command interpreter) or the current batch
script.

EXIT [/B] [exitCode]
  /B          specifies to exit the current batch script instead of
              CMD.EXE.  If executed from outside a batch script, it
              will quit CMD.EXE

          basically if you forget to add /b to your dos script (e.g. if you want to terminate early using exit) you will kill the cmd.exe process and Jenkins will sit until the end of days and not realize...
