Potential problem from Gitlab runner pipeline on windows (powershell)

Dear All

I have encountered some problems with gitlab pipeline script which composed by powershell executor..

I appreciated whoever experienced with this kind of problem comment anything that I could try...

There is no error in command log when I run this pipeline, however matlab.exe seems not operating actually...

# stage

stages:

- command

mfile_command:

stage: command

tags: [my-runner-windows-]

only:

- main

script:

- 'C:\"Program Files"\MATLAB\R2023b\bin\matlab.exe'

- powershell -command "Start-Sleep -Seconds 60"

1. What is the purpose of running MATLAB Desktop with command, and why GitLab?
2. What do you mean by "however matlab.exe seems not operating actually..."? Can you elaborate the issue?

1. My final purpose is running .m file script by pipeline: when I commit my model to repository. I knew that Gitlab tool has supported more security service than any others, and there is an issue which recommend to use Gitlab in my company group.
2. When I launched the pipeline script above, no error appears in log which is presented when I clicked the piepline result. I expected that matlab.exe would operate and can see matlab command window in my monitor of course, but it was not.

(1) Would you mind taking a look at the answer below?

executable not run when invoked from gitlab-runner (#4781) · Issues · GitLab.org / gitlab-runner · GitLab

In short, try the below:

script:

- 'powershell.exe "C:\Program Files\MATLAB\R2023b\bin\matlab.exe"'

(2) If you want to run a script with MATLAB from command window, you can use "-r" option. For example, if you want to run myscript.m via command,

script:

- 'powershell.exe "C:\Program Files"\MATLAB\R2023b\bin\matlab.exe" -r myscript'

Thanks for reply.

I fixed my script as you recommended, but got an error:

$ powershell.exe "C:\Program Files\MATLAB\R2023b\bin\matlab.exe"

17C:\Program : The term 'C:\Program' is not recognized as the name of a cmdlet, function, script file, or operable progra

18m. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Instead, I wrote my script as below :

script:

- powershell.exe "& 'C:\Program Files\MATLAB\R2023b\bin\matlab.exe'"

Yet I could not execute matlab.exe ....

Hi,

A possible cause of such errors in powershell is because of spaces present in the path of executable you are trying to execute. As a workaround you can refer these steps:

• Firstly execute cd '<Path to the bin folder containing the .exe of MATLAB>' in Windows Powershell. Entire path should be in single qoutes.
• Then you can execute this command powershell matlab.exe -r myscript, which would launch MATLAB.

Hope it helps!

Thank you for you reply

Of course, I normally execute my matlab.exe when I command on Powershell prompt directly.

The point is that I could not see same results despite of any errors on build log under gitlab runner pipeline.

My script was written as below:

script:

- echo "script start!!!" # Test

- cd 'C:\Program Files\MATLAB\R2023b\bin\'

- ls # Check path was normally entered

- matlab.exe

Best regards
