You cannot use a reusable workflow from another repository if it uses a composite action. For more information, see "About custom actions."
That said, turns out it's possible to do - below are the details of testing:
Composite action:
# .github/actions/test/action.yml
name: Test
on:
workflow_call:
inputs:
foo:
type: string
description: Foo
required: true
jobs:
test:
runs-on: ubuntu-latest
steps:
- name: Check out
uses: actions/checkout@v3
- name: Echo
run: echo "Hello from reusable workflow! inputs.foo=${{ inputs.foo }}"
- name: Run composite action
uses: micnncim/test-gha-composite-action/.github/actions/test@main
with:
foo: ${{ inputs.foo }}Reusable workflow:
# .github/workflows/_test.yml
name: Test
on:
workflow_call:
inputs:
foo:
type: string
description: Foo
required: true
jobs:
test:
runs-on: ubuntu-latest
steps:
- name: Check out
uses: actions/checkout@v3
- name: Echo
run: echo "Hello from reusable workflow! inputs.foo=${{ inputs.foo }}"
- name: Run composite action
uses: micnncim/test-gha-composite-action/.github/actions/test@main
with:
foo: ${{ inputs.foo }}Workflow using the reusable workflow:
# .github/workflows/test.yml
name: Test
on:
workflow_dispatch:
inputs:
foo:
description: Foo
required: true
jobs:
test:
uses: micnncim/test-gha-composite-action/.github/workflows/_test.yml@main
with:
foo: ${{ github.event.inputs.foo }}Workflow run result:
The repositories used for the testing are available on micnncim/test-gha-composite-action and micnncim/test-gha-reusable-workflow.
