You could potentially do something like
- task: prep
file: scripts/merge.yml
input_mapping: {repo1: workspace-1, repo1: workspace-2, ...}
---
platform: linux
image_resource:
type: docker-image
source:
repository: alpine
params:
#this could whatever path you want
SRC_PATH: src
inputs:
- name: ci-scripts
- name: repo1
- name: repo2
run:
path: scripts/merge.sh
#this output could be use in the next step, it contains the directories you copied in the script below
outputs:
- name: build
#!/bin/sh
set -e
mkdir -p build
#copy around anything you need
cp -rf repo1/../../. build/
cp -rf repo2/../../. build/
cp -rf repo3/../../. build/
#listing content of build folder just checking
ls -la build/
