Windows START command not working from Jenkins Pipeline

问题

I have following code in my script.

echo Trying to kill all node processes.
taskkill /f /im node.exe

echo Running the application...
start npm run prod

echo Success...

The script runs fine if I open a command prompt and run it from there but it doesn't start the npm run process when I run it from Jenkins pipeline.

Strange thing is the build gets success.

Can anyone help me solve this riddle? Thanks. Update - 1 This is the output in Jenkins.

Update - 2 The npm file extension is .cmd and Windows 10 with Jenkins 2.89.4

回答1:

Windows services are not able to open new console windows but START is doing exactly this. So if you are running Jenkins as a service, this won't work. However, your script should work fine if you simply skip the START command. Just npm run prod should be enough.

EDIT:

OK, here is a workaround: if you really need to use the start command, you could create a task with the task scheduler. Righ in there you can put any batch code you want or just point it to a bat file. Use Schtasks /run /TN TaskName to execute your task from Jenkins.
