Check if an asset exists for current commit

Hello,

Would it be possible to use this action to first check if the build is needed? This would save a lot of CI time. For the moment, I have a workflow with the deploy-nightly action but if there is no new commit since last build, the build is still done but not uploaded at the end because the asset already exists.

This please

Just in case, some one else has the same problem, I use this job in my workflow to do this check (XXXXXX needs to be replaced by the release id) :

check-assets:
    runs-on: ubuntu-latest
    outputs:
      needs-build: ${{ steps.assets.outputs.needs-build }}
    steps:
      - name: Check existing assets
        id: assets
        run: |
          hash=${{ github.sha }}
          hash=${hash::6}
          names=( $(curl -sL https://api.github.com/repos/${{ github.repository }}/releases/XXXXXX/assets | jq -r '.[].name') )
          needs_build='true'
          if [ "${{ github.event_name }}" == "repository_dispatch" || "${{ github.event_name }}" == "workflow_dispatch" ]; then
            echo "[WARNING] Nightly workflow triggered manually"
          else
            for name in "${names[@]}"
            do
              basename=${name##*-};
              if [ "${basename%.*}" == "$hash" ]; then
                echo "[WARNING] Commit already built, skipping build"
                needs_build='false'
                break
              fi
            done
          fi
          echo "::set-output name=needs-build::$needs_build"

Then I added this job as dependency of the build job:

  build:
    needs: check-assets
    if: needs.check-assets.outputs.needs-build == 'true'

There is also an action made by Maxzor available here: https://github.com/Maxzor/check-nightly
