Hi @zlee520, this message means that the bash child process is not finished.

As I see it, you are trying to run your application in the background, so in this case the pipeline task will not wait for the background process to finish.
But this should not be the reason for the task to fail.

What problem are you seeing in this case?
And could you explain what you are trying to do and what result do you expect?

hello, I want to start a java app， this task is successfull but the java app not started
running the same command directly on the server can start the app

Hi ,
Do we have any resolution for it ?
We are also facing the same thing.

@KonstantinTyukalov
I have a similar problem than OP but with pwsh task, behaves similarly to bash:

steps:
- pwsh: docker build .

In my exemple I'm trying to build a docker image, which takes around 3 minutes. The problem I'm facing is that the error provokes a failure of the step, even though the build continues and succeeds. I don't want to use continueOnError: true because then I wouldn't fail the step when the docker image fails to build.

As I see it, you are trying to run your application in the background, so in this case the pipeline task will not wait for the background process to finish.
But this should not be the reason for the task to fail.

The step actually runs to completion AND fails because of that error.

I don't understand why this is a topic in the first place.
Pipelines are expected to run long running processes that use STDIO to provide some output.
This shouldn't even yield a warning, the task should simply wait for the process to complete.

Please note, this works fine for me on Windows agents, it only fails on Linux agents.
