[Bug]: Fix unspecific error messages during model lifecycle

[BjoernAtBosch]

Severity

Medium

What release version, tag or commit-hash did you use?

v1.2.1

Current Behavior

If referencing a non-existing vss.json from the AppManifest.json and calling velocitas init -f the model lifecycle has this misleading output:

... > Running post init hook for 'vehicle-model-lifecycle'
Running 'install-deps'... done
Running 'download-vspec'... done
Running 'generate-model'... !
 ›   Error: Program returned exit code: 1

Misleading, because the download-vspec should drop the error and not the generate-model.

Also, there is unspecific message if a non-supported VSS version is used (e.g. VSS version 4.0 at the moment).

Also, if model lifecycle fails during devContainer setup, the failure is not clearly visualize and could be quite easily overseen. This seems especially the case if using GH Code Space.

Steps to Reproduce

1. Change VSS reference in AppManifest to non-existing file
2. Run velocitas init -f

Expected Behavior

Error messages should clearly point out what the issue is

Possible Solution

Catch specific error messages here: https://github.com/eclipse-velocitas/devenv-devcontainer-setup/blob/main/vehicle-model-lifecycle/src/download_vspec.py#L75
