defaults:
run:
working-directory: subdirectoryA

I would guess this only changes the working directory for the inline "run" steps.

From Github docs:

You can use defaults.run to provide default shell and working-directory options for all run steps in a workflow. You can also set default settings for run that are only available to a job. For more information, see jobs.<job_id>.defaults.run. You cannot use contexts or expressions in this keyword.

In that case you would need to set context: subdirectoryA assuming you want to shift the whole context and not just use a custom Dockerfile name. Alternatively you can also use a Git path with : separator.

@tonistiigi thank you for your response. After changing the context it works.
I was confused, because before there is a maven step what executes properly and ls also shown the Dockerfile.

Thank you once again.
