Bamboo build hangs on script that spawns subprocess

Question

Hi,

I have a bamboo build in which one of the tasks is a python script which spawns a subprocess (using subprocess.Popen) to launch a database server which needs to stay alive throughout the rest of the build while tests run.

The script completes successfully, however the build does not proceed to the next task and just hangs. My theory is that bamboo is waiting for the subprocesses to complete as well, before continuing.

Is that what's most likely happening? Is there a way to get bamboo to recognize a script as having completed, even if a subprocess that it's spawned is still running?

Thanks in advance.

I am struggling with the same issue.
I have a simulator for a driver that i want to start as the first build job but it just hangs.

Has this been solved for launching a Windows program?

I've tried this

@echo off
start cmd /c myprogram.exe > nul

But that doesn't quite seem to cut it, Bamboo keeps grabbing the sub-process that is launched and won't progress.

I have what I believe is the same problem.  One of the tasks starts jetty, which returns the correct exit code, but then after the application starts it writes a few more lines to the console.  Bamboo hangs at this point. The solution above solved the problem.
