jobs:
  my-job-1:
    outputs:
      my-output: ${{ steps.step1.outputs.greeting }}
    steps:
      - name: My first step
        uses: docker://alpine:3.18
        id: step1
        run: echo "hello world" > "$CLOUDBEES_OUTPUTS/greeting"
  my-job-2:
    needs: my-job-1
    steps:
      - uses: docker://alpine:3.18
        env:
          OUTPUT1: ${{needs.my-job-1.outputs.my-output}}
        run: |
          echo "my-job-1 said: $OUTPUT1"▼
