Accessing the build environment of another source when using multiple sources

[APemberton1]

Summary

Access the build environment of another source when using multiple sources

Motivation

Now we have multiple sources we need a way to use build env vars from the first source as part of the second. E.g.

  sources:
    - repoURL: https://github.com/xxxx/repo-1
      targetRevision: main
      ref: repo-1
    - repoURL: https://somecharturl.com
      targetRevision: 1.0.0
      chart: somechart
      helm:
        valueFiles:
          - $repo-1/values.yaml
         parameters:
         - name: image.tag
            value: ${ARGOCD_APP_REVISION}

ARGOCD_APP_REVISION resolves to 1.0.0 whereas I want it to resolve to the revision from repo-1 which I manage. Would be very useful as part of automated image version tagging

Proposal

related feat to add multiple sources: schakrad@a928e3b
and issue: #2789

[blakepettersson]

Should be addressed with #12508

[RodrigoMenezes-Vantage]

Any other potential solution to this now that #12508 seems to have been closed and abandoned?

Also running into this issue. Has anyone found a workaround?
