@aaltay after thinking about it a bit more, could you elaborate on "errors
are captured as expected" and I will add some tests for it. I have set it up so
that errors are captured both if the command is not present and raise a more
meaningful error, compare to default "No such file or director" [1]. If the
command is valid but the arguments are incorrect an error is rased giving the
command stating that the arguments are wrong.
@pabloem I have resolved the error in the build concerning the formatting.

> dependency.py calls out to external process to collect dependencies:
> https://github.com/apache/beam/blob/de7cc05cc67d1aa6331cddc17c2e02ed0efbe37d/sdks/python/apache_beam/runners/dataflow/internal/dependency.py#L263
> If these calls fails, the error is not clear. The error only tells what
> failed but does not show the actual error message, and is not helpful for
> users.
> As a general fix processes.py should have general better output collection
> from failed processes.
