Execute WIndows bat file in Jenkins

Question

I am using Jenkins 2.46.1 I have a build pipeline plugin installed and I want to execute a Windows batch file in it. The batch file should execute in a new command window and not on jenkins console output. I give the below Jenkins pipeline groovy script:

node {  
    stage 'Init'
    bat '''
        call C:\\myprj\\mybat.bat stop
        EXIT /B 0
    '''
    stage 'Deploy'
    bat '''call C:\\myprj\\mybat.bat'''
}

In the init stage, I want to kill the process if it is already open and in stage deploy it should open a new command window and run my batch file. The problem is that the above does not work. The build is succesful but no command window opens up. Pls suggest

Technically, to do what you're asking you should be able to run

bat 'start cmd.exe /c C:\\myprj\\mybat.bat'

This will launch a new command windows (cmd.exe) and run the batch file given. Depending how your Jenkins slave is running you may not see anything. (eg if it's running as a windows service or different user, you won't see anything)

Jenkins is running as a windows service. Is there no way in this case that I can open a new command window? – user5917011 Apr 22 '17 at 06:14
The reason why I want it to open in a new command window is because the batch file will run a server. THe command window remains opened as long as the server is running. So the build will always show as 'getting executed' and never as 'completed' – user5917011 Apr 22 '17 at 07:08
There is no easy way that I know of, it's part of the design for windows services. You may be able to hang the bat process indefinitely with a loop. Of course, this then ties up that build node. If you really want to hack something together you can have a scheduled task that is triggered by an event in the event log, then have your bat file/service create that event. – Kendall Trego Apr 24 '17 at 20:14

Alternative solution if the agent is running in a service and you would like to get output:

bat(readFile("mybat.bat"))

Note: The bat file will need to be in your workspace.

Additional Note: You are no longer running the bat file from its original location. Instead it is being run from a temp location created by the underlying durable task system. This means things like %~dp0 in your script are not going to return the paths you might expect.
